Re: how to make sure all the index docs flushed to the index files
Hi Another werid problem. When we setup the autocommit properties, we suppose that the index fille will created every commited.So that the size of the index files will be large enough. We do not want to keep too many small files as [1]. How to control the size of the index files.

Problem with SynonymFilter and StopFilterFactory
Hi,
I have encoutered a problem applying StopFilterFactory and
SynonimFilterFactory. The problem is that SynonymFilter removes the gaps
that were previously put by the StopFilterFactory. I'm applying filters in
query time, because users need to change synonym lists frequently.
This is my schema, and an example of the issue:
String: "documentacion para agentes"
org.apache.solr.analysis.WhitespaceTokenizerFactory
{luceneMatchVersion=LUCENE_35}
position1 2 3
term text documentaciónpara agentes
startOffset 0 14 19
endOffset 13 18 26
org.apache.solr.analysis.LowerCaseFilterFactory
{luceneMatchVersion=LUCENE_35}
position1 2 3
term text documentaciónpara agentes
startOffset 0 14 19
endOffset 13 18 26
org.apache.solr.analysis.StopFilterFactory {words=stopwords_intranet.txt,
ignoreCase=true, enablePositionIncrements=true,
luceneMatchVersion=LUCENE_35}
position1 3
term text documentación agentes
startOffset 0 19
endOffset 13 26
org.apache.solr.analysis.SynonymFilterFactory
{synonyms=sinonimos_intranet.txt, expand=true, ignoreCase=true,
luceneMatchVersion=LUCENE_35}
position1 2
term text documentación agente
archivo agentes
typeSYNONYM SYNONYM
SYNONYM SYNONYM
startOffset 0 19
0 19
endOffset 1326
13 26
As you can see, the position should be 1 and 3, but SynonymFilter removes
the gap and moves token from position 3 to 2
I've got the same problem with Solr 3.5 y 4.0.
I don't know if it's a bug or an error with my configuration. In other
schemas that I have worked with, I had always put the SynonymFilter
previous to StopFilter, but in this I prefered using this order because of
the big number of synonym that the list has (i.e. I don't want to generate
a lot of synonyms for a word that I really wanted to remove).
Thanks,

Re: how to make sure all the index docs flushed to the index files
Hi Shawn Thank your very much for your reponse. I lauch the full-import task on the web page of solr/admin . And I do check the commit option. The new docs would be committed after the operation. The commit option is defferent with the autocommit,right? If the import datasets are too large that leads to poor performance or other problems ,such as [1]. The exception that indicate that -Too many open files-,we thought is because of the ulimit.

You need to turn on autoCommit in your solrconfig.xml so that there are hard commits happening on a regular basis that flush all indexed data to disk and start new transaction log files.

As results ,I give up. I don't know what the exception was about, but it is likely that it WAS replaying the log. With 4.1GB of transaction log, that's going to take a LONG time, during which Solr will be unavailable. It always replays the entire transaction log. The key, as mentioned above, is in keeping that log small. Here's a wiki page about the slow startup problem and an example of how to configure autoCommit to deal with it: http://wiki.apache.org/solr/SolrPerformanceProblems#Slow_startup There's a lot of other good information on that page.

2 question about solr and lucene
Hi, guys:
I met two questions about solr and lucene, wish people to help out.
use payload query but can NOT with numerical field type. for example:
I implemented my own requesthandler, refer to
http://hnagtech.wordpress.com/2013/04/19/using-payloads-with-solr-4-x/
I query in solr:sinaTag:operate
solr response:
"numFound": 2,
"start": 0,
"maxScore": 99,
"docs": [
{
"id": "1628209010",
"followersCount": 752,
"sinaTag": "operate|99 C2C|98 B2C|97 OnlineShopping|96 E-commercial|94",
"score": 99
},
{
"id": "1900546410",
"followersCount": 1002,
"sinaTag": "Startup|99 Benz|98 PublicRelation|97 operate|96 Activity|95
Media|94 AD|93 Vehicle|92 ",
"score": 96
}
This work well.
But query with combined with other numberical condition, such as:
sinaTag:operate and followersCount:[752 TO 752]
{
"responseHeader": {
"status": 0,
"QTime": 40
},
"response": {
"numFound": 0,
"start": 0,
"maxScore": 0,
"docs": []
}
}
According these dataset, the first record should be responsed rather than
NOT FOUND.
I not know why.
2. About string field fuzzy match filtering, how to get the score? what the
formula is?
When I used two or several string fuzzy match, probable AND or OR, how to
get the score? what the formula is?
Might I implement myself score formula class which interface or abstract
class to extend ?
Thanks in advance.
how to make sure all the index docs flushed to the index files
Hi I'm using the DIH to import data from oracle database with Solr4.4 Finally I get 2.7GB index data and 4.1GB tlog data.And the number of docs was 1090. At first, I move the 2.7GB index data to another new Solr Server in tomcat7. After I start the tomcat ,I find the total number of docs was just half of the orginal number. So I thought that maybe the left docs were not commited to index files,and the tlog needed to be replayed . Sequently , I moved the 2.7GB index data and 4.1GB tlog data to the new Solr Server in tomcat7. After I start the tomcat,an exception comes up as [1]. Then it halts.I can not access the tomcat server URL. I noticed that the CPU utilization was high by using the comand: top -d 1 | grep tomcatPid. I thought solr was replaying the updatelog.And I wait a long time and it still was replaying. As results ,I give up. So I want to make sure after I finished the DIH import process ,whether the whole index was flushed into the index data files. Is there any steps I missed? How to make sure all the index were commited into the index files?.

SPLITSHARD failure right before publishing the new sub-shards
Hi Solr experts,
I am using Solr 4.4 with ZK 3.4.5, trying to split "shard1" of a
collection named "body". There is only one core on one machine for this
collection. When I call SPLITSHARD to split this collection, Solr is
able to create two sub-shards, but failed with a NPE in SolrCore.java
while publishing the new shards. It seems that either the updateHandler
or its updateLog is null, though they work fine in the original shard:
SolrCore.java
if (cc != null && cc.isZooKeeperAware() &&
Slice.CONSTRUCTION.equals(cd.getCloudDescriptor().getShardState())) {
// set update log to buffer before publishing the core
862: getUpdateHandler().getUpdateLog().bufferUpdates();
cd.getCloudDescriptor().setShardState(null);
cd.getCloudDescriptor().setShardRange(null);
}
Here are the details. Any pointers to aid debugging this issue is
greatly appreciated!

Sorry but I've fixed some typos, updated text:
Hello Solr experts,
For some strange reason, collection alias does not work in my Solr
instance when more than one collection is used. I would appreciate your
help.
# Here is my setup, which is quite simple:
Zookeeper: 3.4.5 (used to upconfig/linkconfig collections and configs
for c1 and c2)
Solr: version 4.4.0, with two collections c1 and c2 (solr.xml included)
created using remote core API calls

1. Solr queries to each individual collection works fine:

2. CREATEALIAS name=cx for c1 or c2 alone (e.g. 1-1 mapping) works fine:

BTW, I've spent a lot of time figuring out how to make zookeeper and
solr work together. The commands are not complex, but making them work
sometimes requires a lot of digging online, to figure out missing jars
for zkCli.sh, etc. I know a lot of things are changing since Solr 4.0,
but I really hope the Solr documentation can be better maintained, so
that people won't have to spend tons of hours figuring out simple steps
(albeit complex under the hood) like this. Thanks!

CREATEALIAS does not work with more than one collection (Error 503: no servers hosting shard)
Hello Solr experts,
For some strange reason, collection alias does not work in my Solr
instance when more than one collection is used. I would appreciate your
help.
# Here is my setup, which is quite simple:
Zookeeper: 3.4.5 (used to upconfig/linkconfig collections and configs
for c1 and c2)
Solr: version 4.4.0, with two collections c1 and c2 (solr.xml included)
created using remote core API calls
# Symptoms:
1. Solr queries to each individual collection works fine:
http://localhost:8983/solr/c1/select?q=*:*
http://localhost:8983/solr/c2/select?q=*:*
2. CREATEALIAS name=cx for c1 or c2 alone (e.g. 1-1 mapping) works fine:
http://localhost:8983/solr/cx/select?q=*:*
3. CREATEALIAS name=cx for c1 and c2 does not work:
# Solr request/response to the collection alias (success):
http://localhost:8983/solr/cx/select?q=*:*
5032*:*no
servers hosting shard: 503
# Solr query using the alias fails with Error 503: "no servers
hosting shard"
curl -s
"http://localhost:8983/solr/admin/collections?action=CREATEALIAS&name=cx&collections=c1,c2";

BTW, I've spent a lot of time figuring out how to make zookeeper and
solr work together. The commands are not complex, but making them work
sometimes requires a lot of digging online, to figure out missing jars
for zkCli.sh, etc. I know a lot of things are changing since Solr 4.0,
but I really hope the Solr documentation can be better maintained, so
that people won't have to spend tons of hours figuring out simple steps
(albeit complex under the hood) like this. Thanks!

TokenizerFactory from 4.2.0 to 4.3.0
TokenizerFactory changed, incompatibly with subclasses, from 4.2.0 to 4.3.0. Subclasses must now implement a different overload of create, and may not implement the old one. Has anyone got any devious strategies other than multiple copies of code to deal with this when supporting multiple versions of Solr?

Re: Re-Ranking results based on DocValues with custom function.

:

can you describe what you want your custom function to look like? it may
already be possible using the existing functions provided out of hte box -
just neeed to combine them to build up the mathc expression...

when writing a custom plugin like this, the best thing to do is look at
the existing examples of that plugin. almost all of hte built in
ValueSourceParsers are really trivial, and can be found in tiny anonymous
classes right inside the ValueSourceParser.java...
For example, the function ot divide the results of two other fnctions...
addParser("div", new ValueSourceParser() {
@Override
public ValueSource parse(FunctionQParser fp) throws SyntaxError {
ValueSource a = fp.parseValueSource();
ValueSource b = fp.parseValueSource();
return new DivFloatFunction(a, b);
}
});
..or, if you were trying to bundle that up in your own plugin jar and
register it in solrconfig.xml, you might write it something like...
public class DivideValueSourceParser extends ValueSourceParser {
public DivideValueSourceParser() { }
public ValueSource parse(FunctionQParser fp) throws SyntaxError {
ValueSource a = fp.parseValueSource();
ValueSource b = fp.parseValueSource();
return new DivFloatFunction(a, b);
}
}
and then register it as...
depending on your needs, you may also want to write a custom ValueSource
implementation (ie: instead of DivFloatFunction above) in which case,
again, the best examples to look at are all of the existing ValueSource
functions...

Re: SOLR 4.2, slaves replicating reporting higher version number than master
Looks much like what I'm encountering. Guessing that will go away once I update solr, just wanted to make sure it wasn't a real bug. Entirely possible we are getting some "empty commits" given the nature of the index maintenance. Thanks for the pointer!

Dynamic row sizing for documents via UpdateCSV
Hello, I am using UpdateCSV to load data in solr. Currently I load this schema with a static set of values: userid,name,age,location john8322,John,32,CA tom22,Tom,30,NY But now I have this usecase where john8322 might have a state specific dynamic field for example: userid,name,age,location, ca_count_i john8322,John,32,CA, 7 And tom22 might have different dynamic fields: userid,name,age,location, ny_count_i,oh_count_i tom22,Tom,30,NY, 981,11 So is it possible to pass different columns sizes for each row, something like this: john8322,John,32,CA,ca_count_i:7 tom22,Tom,30,NY, ny_count_i:981,oh_count_i:11 I understand that the above syntax is not possible, but is there any other way of solving this problem? -- Thanks, -Utkarsh

Basically what this means is that this query will be run when Solr first starts up, and never run again after that. Make it a newSearcher instead of firstSearcher, and it will get run every time a new searcher gets created, and it might solve your problem. For further troublsehooting if the change above doesn't help, how big is your index, and how much RAM does the machine have? We already know what your java heap is (2GB minimum, 4GB maximum).

That is a very common way for installs requiring NRT updates to get configured. NRTCachingDirectoryFactory, which is the directory class used in the example since 4.0, is a wrapper around MMapDirectoryFactory, which is the old default in 3.x. For soft commits, the NRT directory keeps small commits in RAM rather than writing it to the disk, which makes the process of opening a new searcher happen a lot faster. http://lucene.apache.org/core/4_4_0/core/org/apache/lucene/store/NRTCachingDirectory.html If your index rate is very fast or you index large amounts of data, the NRT directory doesn't gain you much over MMap, but because we made it the default in the example, it probably doesn't have any performance detriment.

Re: SOLR 4.2, slaves replicating reporting higher version number than master
Sounds like perhaps you are getting confused by this... https://issues.apache.org/jira/browse/SOLR-4661 ...if that is the situation then it's not a bug you need to worry about, just a confusion in how the ReplicaitonHandler reports it's stats -- the newer UI makes it more clear what numbers you are looking at. If that doesn't looke like the problem you are seeing, then more detail on how to reproduce what you are seeing would be helpful (replicaiton configs, logs from amster & slave, etc...) -Hoss
SOLR 4.2, slaves replicating reporting higher version number than master
Having a strange intermittent issue with my 1 master, 3 slave solr 4.2 setup. On occasion, after indexing the master and replicating across the three slaves, each slave will start reporting they are one generation ahead (525 vs. 524 on the master) and thus out of sync. Replication runs appear to do nothing, and it seems to not really be affecting performance, it's just tickling my admin nerves. Any suggestions of what to look at? Just upgrade solr perhaps? 4.2 might be getting rather old...
Re: sorting using org.apache.solr.client.solrj.SolrQuery not working
: In the log i see the sorting column as "LAST_NAM".
: Is there a difference between "LAST_NAM asc" and "LAST_NAM+asc"...I see only
: this diff?
the log message you are looking at is showing you the request params
recieved by the handler fro mthe client, with URL escaping -- so the "+"
you see is the url escaing of the " " sent by the client.
can you show us the declaration for the handler name
you are using?
If you are seeing theresults sorted by a differnet field then the one you
specified in the client, then it has to be specified somehwere -- I'm
guessing since it's not explicit in that log message that it's "/select"
but it could also be whatever you have configured asthe default="true".
my best guess is that the requestHandler has some init params that set the
sot option as an invariant so that you can't override it.
:
"params={sort=LAST_NAM+asc&start=0&q=*:*&wt=javabin&fq=(LAST_NAM:*D*)+AND++-CLAI_RISK_MNGT_FLG+:+Y+&version=2&rows=30}
: hits=196 status=0 QTime=2 "
one other thing to sanity check: try loading your requestHandler, with all
ofthose params (except for "wt=javabin") in a browser window, and double
check which order the results come back -- just to verify that the results
really are getting sorted incorrectly on the solr side and that the
problem isn't some other bit of javacode you have re-sorting the results
that get returned.
if you load the URL in your browser, yo ucan also add echoParams=all to
see every param used in the request, even if it is an invariant specified
in the requestHandler config.

Re: Solr PingQuery
I want to add one more thing for Shawn about Zookeeper. In order to have quorum, you need to have half the servers plus one available. Because of that let's assume you have 4 machine of Zookeeper and two of them communicating within them and other two of them communicating within them. Assume that this two zookeeper sets (each of them has two zookeeper node) can not communicate with each other. This will result with a brain split. So the rule is simple. In order to have quorum, you need to have half the servers plus one available because there can not be two different sets at any time that has a number of half the servers plus one. There can be only one. 2013/9/15 Shawn Heisey > On 9/14/2013 6:57 AM, Prasi S wrote: > > I use SolrPingResponse.getStatus method to start indexing to solr.

Re: sorting using org.apache.solr.client.solrj.SolrQuery not working
Shawn,
I am doing exactly same. Data output is not sorting on "LAST_NAME"
column , but it is always sorting on different column "CLAIM_NUM", and I am
not adding this sorting condition( sort on CLAIM_NUM).
solrQuery.setQuery("*:*");
solrQuery.setSort("LAST_NAM",SolrQuery.ORDER.asc);
solrQuery.setFilterQueries("String Query");
In the log i see the sorting column as "LAST_NAM".
Is there a difference between "LAST_NAM asc" and "LAST_NAM+asc"...I see only
this diff?
"params={sort=LAST_NAM+asc&start=0&q=*:*&wt=javabin&fq=(LAST_NAM:*D*)+AND++-CLAI_RISK_MNGT_FLG+:+Y+&version=2&rows=30}
hits=196 status=0 QTime=2 "
CLAI_IDN
I also tried addOrUpdateSort and addSort, But it is always sorting on
CLAI_CLM_NUM, not sure why?

RE: Spellcheck compounded words
I would investigate Hoss's suggestion and look at warming queries. In some cases I've seen "maxCollationTries" in warming queries to cause a hang. Unless you're trying to build your spellcheck dictionary during warming, you can safely turn spellcheck off for all warming queries.

Re: 2 question about solr and lucene
Are you saying you're trying to put payloads on the numeric data?
If that's the case I don't know how that works. But a couple of things:
sinaTag:operate and followersCount:[752 TO 752]
is incorrect, you must capitalize the and as
sinaTag:operate AND followersCount:[752 TO 752]
Your syntax _should_ work since [] is inclusive, but
I'd just try with 751 TO 753] once to be sure.
Attach &debug=all to your query and you'll see exactly how the
query is parsed. You'll also see exactly how the scores are
calculated in a long, complex bit of output. I _think_ that
fuzzy and wildcards do a "constant score query", so don't be
surprised if the calculations show you that the fuzzy matches don't
change the score.
Best,
Erick

Slow query at first time
Hi,
I´m trying to make a search with Solr 4.4, but in the first time the search
is too slow. I have studied about pre-warm queries, but the query response
is the same after putting it. Can anyone help me? Here´s a piece of
solrconfig.xml:
codigoRoteiro:95240816
0
20
in the schema.xml:
codigoRoteiro
When I start Solr, the following message is shown:
$ java -server -Xms2048m -Xmx4096m -Dsolr.solr.home="./oracleCore/solr"
-jar start.jar
.
.
.
8233 [searcherExecutor-4-thread-1] INFO org.apache.solr.core.SolrCore û
QuerySenderListener done.
8235 [searcherExecutor-4-thread-1] INFO org.apache.solr.core.SolrCore û
[db] Registered new searcher
Searcher@30b6b67dmain{StandardDirectoryReader(segments_6:34
_f(4.4):C420060)}
And here´s my solrj sample code:
SolrServer solrServer = new HttpSolrServer(solrServerUrl);
SolrQuery query = new SolrQuery();
query.setQuery("codigoRoteiro:95240816");
query.set("start", "0"); query.set("rows", "20");
query.addField("codigoRoteiro"); query.addField("rowidString");
query.addField("descricaoRoteiro"); query.addField("numeroDias");
query.addField("numeroNoites"); query.addField("dataSaida");
Date initialTime = new Date(); QueryResponse rsp = server.query( query );
SolrDocumentList docs = rsp.getResults(); Date finalTime = new Date();
System.out.println("Total timel: " +
(finalTime.getTime()-initialTime.getTime()) + " ms");
The response time is arround 200 ms. If I remove the prewarm query, the
response time doesn´t change. Shouldn´t the response time be minor when
using pre-warm query?
Thanks in advance,

Re: How to make Solr complex Join Query patch in java
I'd start by taking a very hard look at my data model and seeing if I can make redefine the model (as translated from the DB you may be coming from). Solr does not excel at what RDBMSs are designed to do. Really. I predict that if you just try to make Solr into a RDMBS, you'll expend a lot of effort and not be satisfied with the results. For instance, do you expect to support joins across shards, i.e. distributed support? What about "block joins"? Sub-selects (again if so, what about distributed)? Grouping? But if you absolutely insist on trying this, look at the existing Join code. Take a look through any classes in the Solr/Lucene source tree starting with either Join or BlockJoin. Note that they are two very different capabilities so be aware of that as you look through them.

how soft-commit works
Can anyone explain me the following things about soft-commit? -For searches o access new documents I think a new searcher is opened after a soft commit. How does the near realtime requirement for soft commit match with the potentially long time taken to warm up caches for the new searcher? -Is it a good idea to set openSearcher=false in auto commit and rely on soft auto commit to see new data in searches? thanks Matteo Grolla
Re: Frequent softCommits leading to high faceting times?
Soft commits are not free, they invalidate certain caches which then have to be reloaded. I suspect you're hitting this big time. The question is always "do you really, really _need_ 1 second latency?". Set the soft commit interval to be as long as your application can stand IMO. And it may have nothing to do with facets, since things like your filterCache autowarming is done on soft commit. Ditto for the other caches you've configured in solrconfig.xml. But one thing to watch is the size of your tlog. Transaction logs are only truncated on hard commits, and can get replayed on restart. So you're risking long restart times here. See: http://searchhub.org/2013/08/23/understanding-transaction-logs-softcommit-and-commit-in-sorlcloud/ FWIW, Erick On Mon, Sep 16, 2013 at 1:43 AM, Rohit Kumar wrote: > Hi, > > We are running *SOLR 4.3* with 8 Gb of index on > > Ubuntu 12.04 64 bits > Intel(R) Xeon(R) CPU E5-2650 0 @ 2.00GHz Single core. > 16GB RAM > > > We just started using the autoSoftCommit feature and noticed the facet > queries slowed down from milliseconds taking earlier to a minute.

Which version of Solr are you running? (the post you replied to was about Solr 3.3, but the latest version now is 4.4.) Please provide configuration details and the query you are running that causes the problem. Also explain exactly what the problem is (query never returns?).

Re-Ranking results based on DocValues with custom function.
Hi! I'm having quite an index with a lot of text and some binary data in the documents (numeric vectors of arbitrary size with associated dissimilarity functions). What I want to do is to search using common text search and then (optionally) re-rank using some custom function like http://localhost:8983/solr/select?q=*:*&sort=myCustomFunction(var1) asc I've seen that there are hooks in solrconfig.xml, but I did not find an example or some documentation. I'd be most grateful if anyone could either point me to one or give me a hint for another way to go :) Btw. Using just the DocValues for search is handled by a custom RequestHandler, which works great, but using text as a main search feature, and my DocValues for re-ranking, I'd rather just add a function for sorting and use the current, stable and well performing request handler. cheers, Mathias ps. a demo of the current system is available at: http://demo-itec.uni-klu.ac.at/liredemo/ -- Dr. Mathias Lux Assistant Professor, Klagenfurt University, Austria http://tinyurl.com/mlux-itec
2 question about solr and lucene
Hi, guys:
I met two questions about solr and lucene, wish people to help out.
use payload query but can NOT with numerical field type. for example:
I implemented my own requesthandler, refer to
http://hnagtech.wordpress.com/2013/04/19/using-payloads-with-solr-4-x/
I query in solr:sinaTag:operate
solr response:
"numFound": 2,
"start": 0,"maxScore": 99,"docs": [ {"id": "1628209010",
"followersCount": 752,
"sinaTag": "operate|99 C2C|98 B2C|97 OnlineShopping|96 E-commercial|94",
"score": 99
},
{"id": "1900546410",
"followersCount": 1002,
"sinaTag": "Startup|99 Benz|98 PublicRelation|97 operate|96 Activity|95
Media|94 AD|93 Vehicle|92 ",
"score": 96
}
This work well.
But query with combined with other numberical condition, such as:
sinaTag:operate and followersCount:[752 TO 752]
{"responseHeader": {"status": 0,"QTime": 40
}, "response": {"numFound": 0,"start": 0,
"maxScore": 0,"docs": [] }
}
According these dataset, the first record should be responsed rather than
NOT FOUND.
I not know why.
2. About string field fuzzy match filtering, how to get the score? what the
formula is?
When I used two or several string fuzzy match, probable AND or OR, how to
get the score? what the formula is?
Might I implement myself score formula class which interface or abstract
class to extend ?

One of the very useful properties of wear-levelling on SSD's is the wear status of the drive can be queried. When the drive nears its EOL, replace it. As Lucene mainly uses bulk writes when updating the index, I will add that the chances of wearing out a SSD by using it primarily for Lucene/Solr is pretty hard to do, unless one constructs a pathological setup. Your failure argument is thus really a claim that SSDs are not reliable technology. That is a fair argument as there has been some really rotten apples among the offerings. This is coupled with the fact that is is still a very rapidly changing technology, which makes it hard to pick an older proven drive that is not markedly surpassed by the bleeding edge. > So far I'm not aware of any RAID solutions that offer TRIM support, > and without TRIM support, an SSD eventually has performance problems. Search speed is not affected as "only" write performance suffers without trim, but index update speed will be affected. Also, while it is possible to get TRIM in RAID, there is currently only a single hardware option: http://www.anandtech.com/show/6161/intel-brings-trim-to-raid0-ssd-arrays-on-7series-motherboards-we-test-it Regards, - Toke Eskildsen, State and University Library, Denmark
Re: solr/document/select not available
If you have two cores, then the core name should be in your URL.
Http://host:8983/solr//select?q=blah
Or you can set a default core in solr.xml.

Re: what does "UnInvertedField; UnInverted multi-valued field" means and how to fix it
Hay, thanks for the reply.
So after a full day spent only on trying to figure this out, I have found
the cause (spellcheck component)... but not the solution.
Se my other post with the subject "*spellcheck causing Core Reload to hang*".
I have explained it there.
Thanks a lot.

Re: spellcheck causing Core Reload to hang
Yes I have tried Spellcheck=false and with that everything works just fine. But I do need Spell check component so I cant just leave it off.

Re: spellcheck causing Core Reload to hang
Hi, Basically, it hangs only on "core Reload" and not during queries. Furthermore, there is never any error reported in the logs, in fact the log only records until Core-Reload call. If I shut down and restart Solr, the next time it wont start, and still no errors in the log.
