Re: MySQL Exception: Communications link failure WITH DataImportHandler

[Jienan Duan]

Hi all:
I have resolved this problem by configuring a jndi datasource in tomcat.
But I still want to find out why it throw an exception in DIH when I
configure datasource in data-configure.xml but a jndi resource.

Regards.

Can two Solr share index?

[Alex King]

Hi all,
We use Solr to build a search service for our customers. We have got one
core on one physical machine. When our site will be ready and running it
could potentially be very busy with serving search results to users. But I
want to perform indexing of new documents without affecting Solr search
performance. (there can be huge amount of documents at one time)
We figured out that we can have one Solr only for search and another (or
more in the future) Solr to do the indexing. Those Solrs should eventually
have the same index (it isn't neccessery to synchronize those indexes every
time new document was added, but I want the search Solr to get new
documents, lets say ones in a week).
So my question is: it a good idea, at all? ;) And how can I accomplish
this? Can Solrs share index? Or should I copy the index from indexing
machine to search machine (how to do it technically? is there some special
tool for this purpose?)
Regards,
Alex

Re: Atomic Multicore Operations - E.G. Move Docs

[Nicholas Ball]

I've been close to implementing a 2PC protocol before for something else,
however for this it's not needed.
As the move operation will be done on a single node which has both the
cores, this could be done differently. Just not entirely sure how to do it.

When a commit is done at the moment, the core must get locked somehow, it
is at this point where we should lock the other core too if a move
operation is being executed.

org.apache.solr.client.solrj.SolrServerException: java.net.SocketException: Unrecognized Windows Sockets error: 0: JVM_Bind

[Kashif Khan]

Does anybody know why this error shows up? 

org.apache.solr.client.solrj.SolrServerException: java.net.SocketException:
Unrecognized Windows Sockets error: 0: JVM_Bind

I have developed a solr plugin and have been querying to my plugin with
multiple requests then only this error shows up. if i request single query
to the plugin it wont show this problem.

This looks like the version number at the top of the schema has more than one 
dot,
eg "1.2.3". Solr parses version as a floating point number, so it must be 
"1.23" instead.

Re: missing core name in path

[Jack Krupansky]

Compare your current schema.xml to a previous known good copy (or to the 
original from the Solr example) and see what changes have occurred. Maybe 
you were viewing it in some editor and accidentally hit some keys that 
corrupted the format.


And, tell us what release of Solr you are using.

Sort on dynamic field

[Peter Kirk]

Hi, a question about sorting and dynamic fields in "Solr Specification Version: 
3.6.0.2012.04.06.11.34.07".

I have a field defined like


Where type int is


If I perform a search, which returns 13 documents, and sort by a field called 
"item_group_int", then it almost produces the results I expect. The only thing 
I don't expect is that one document in the results, which does not have a field 
called "item_group_int", appears in the sort order as number 2. 

I think this has something to do with the fact that one of the other documents 
has a value of 0 for this field - it comes first in the sort.

How do I relegate documents which do not possess the requested sort-field to 
the last positions in the results?

Thanks,
Peter

Your opinion please concerning prod' installation

[Bruno Mannina]

Dear All,

I would like to present you what I want to do to install Solr on a brand 
new production server.


1. uninstall apache-tomcat provides with the standard Ubuntu 12.04
2. uninstall Sun Java provides with the standard Ubuntu 12.04

3. install Java 7
4. install apache-tomcat

5. download Solr 3.6.1 (or do you think I can download the 4.0?)

6. secure server (ok but how)

Thanks for your comment!

Of course if you have a link that details these processes It will be 
great. (not one page for each step I have them)


Have a nice day !
Bruno

How to index multivalued field tokens by their attached metadata?

[Fuu]

Hello all Solrians.

I'm fairly new to Solr, having only played with it for about a month now.
I'm working with the Solr 4.0.0-Alpha release, trying to figure out a proper
approach to an indexing problem, but the methods I've come up with are not
panning out. I describe below the problem and my 3 attempts of solving it. I
hope someone here has had similar issues and solved them or can tell me that
my current ones are no good. :)

Problem: I have a dataset that consists of email type of documents. From
these documents I need to extract to extract certain tokens, attach meta
information to each token and then make them searchable based on the
attached meta information. If it works, I could search the index for tokens
that were in a document created in certain data range, or based on any other
metadata like this attached to the token. 

Basically: For each document on disk => X amount of extracted token based
documents in the index.

Attempt one: As a starting point I first used a PatternTokenizer to get  the
tokens that I want, so each indexed document now would have a multivalued
field of tokens. I then wrote a TokenFilter that attached the metadata to
each token as a payload. I tried searching by payload and discovered it only
worked if I used the token as search parameter. Apparently searching by
keywords in token payload is not implemented yet? 

Attempt two: I read about PpdateRequestProcessors and processor chains, and
tried writing a Processor that would take in a document, check if it has a
field with my tokens extracted using the TokenFilter from the first approach
in it, and then write hand out each token as a separate document to the next
processor. I couldn't figure out how to do this, apparently once you call
super.processAdd() it jumps to the next document, rather than allow me to
insert new document based on next token of the current document.

Attempt 3: Use a Lucene IndexWriter directly from the custom
UpdaterequestProcessor to write the created meta-token documents to a
separate index. As a concept it should work, but how would this second index
conform to it's Solr schema if i directly write data to an Index? I assume
that I would configure the index as a second core with it's own schema and
search parameters. Can Solr still query the index normally?

As you can see I'm little bit at loss on how to implement this. Are all of
the above approaches are bad? Have I misunderstood one of them and it should
actually work?  I could go back to basics and write a document processor in
Python to do all the parsing and patternmatching and token extraction
outside of Solr and just feed it documents to index, but this seems like
something that Solr should do and I'm just not seeing The Right Way. 

Regards,
Juha

Re: How to index multivalued field tokens by their attached metadata?

[Jack Krupansky]

It would help if you could give a simple, contrived example of the kind of 
input you want to process, what tokens you consider special, their metadata, 
and the Solr documents you hope to generate, with the schema definition 
(summarized.) But keep it simple, at first.


That said, as a general rule, any "complex processing" is best done upstream 
from Solr. Sure, you can do some interesting processing in an update 
handler, including with scripts now, but just don't go overboard.


In fact, maybe you might be better off by first writing your processing as a 
standalone program that feeds Solr XML documents to Solr, get that working, 
and THEN decide whether and how that processing might be integrated more 
tightly with Solr.


But, start by defining the inputs, processing, and output as requested 
above.

Sharding and Replication setup

[erolagnab]

Hi all,

I'm trying to setup Solr in current environment to provide high availabilty
and fault torrenlance infrastucture.
What I have is:
1. 2 physical servers running 2 Tomcats
2. A load balancer doing round-robin requests to 2 Tomcats

After reading thru different posts
(http://lucidworks.lucidimagination.com/display/solr/Scaling+and+Distribution,
http://www.slideshare.net/sourcesense/sharded-solr-setup-with-master), I'm
thinking of having the setup as in the image attached 
http://lucene.472066.n3.nabble.com/file/n4001642/Solr_Sharding_and_Replication_HA.png
Solr_Sharding_and_Replication_HA.png 

Basically, it's a combination of sharding and replication.

Server 1, I have a 3-core Solr instance. e.g.: Master 1, Slave 1 (replicated
locally from Master 1) and Slave 2 (replicated remotely from Master 2 in
Server 2)
Server 2, I have similar setup, e.g.: Master 2, Slave 2 (replicated locally
from Master 2) and Slave 1 (replicated remotely from Master 1 in Server 1)

The indexing request can come to Master 1 or Master 2 hence Slave 1 and
Slave 2 become high available shards (as in both servers).

The search requests are served by a virtual coordinator (can hit slave 1
core or slave 2 core directly with shards parameter) to combine results from
Slave 1 and Slave 2.

I haven't done the actual implementation yet. Just post here so to hear any
suggestion/recommendation/pitfalls/gotchas on this setup from experts.

Very appreciate your attention.

Cheers,

Trung

Re: SOLR3.6:Field Collapsing/Grouping throws OOM

[prosens]

"*Solr's sorting reads all the unique values into memory whether or not they
satisfy the query...*"
Is it not a overhead for any query? Any reason why it is done on entire
result set and not on the query? Is there a way to avoid this?

solr 4 degraded behavior failure

[Buttler, David]

Hi all,
I am testing out the could features in Solr 4, and I have a observation about 
the behavior under failure.

Following the cloud tutorial, I set up a collection with 2 shards.  I started 4 
servers (so each shard is replicated twice).  I added the test documents, and 
everything works fine.  If I kill one or two servers, everything continues to 
work.  However, when three servers are killed, zero results are returned.  This 
is an improvement over previous versions of the cloud branch where having 
missing shards would result in an error, but I would have expected fewer 
results rather than zero results.

It turns out that there is a parameter that can be added to a query to get 
degraded results, but it is not described on the Solr cloud page.  It is on the 
DistributedSearch page, but it is poorly defined, and difficult to locate 
starting from the cloud page.

The way to get degraded results is to append:
shards.tolerant=true
to your Solr query.

Dave

solrcloud/solr4: how to specify a new configuration to use, superseding previous configs w/o deleting‏

[Zulu Chas]

I am trying to set up a solrcloud/solr4.0.0-beta with multiple cores, multiple 
shards, and a separate zookeeper process, but I think the exact details are 
less important than the method of bootstrapping zookeeper with the 
configs.Since I'm running zookeeper separately, I'd like to be able to version 
solrcloud configs and drop them into zookeeper over time without necessarily 
having to overwrite or immediately delete old ones.
After starting zookeeper using zkServer.sh start, I've been initially 
bootstrapping it with:

java -Dsolr.solr.home=instance1 -Djetty.port=8501 
-Djetty.home=$SOLR_HOME/solrcloud 
-Dbootstrap_confdir=$SOLR_HOME/solrcloud/instance1/core0/conf 
-Dcollection.configName=A01 -DnumShards=2 -DzkHost=localhost:2181 -jar start.jar

and then starting a second shard with:

java -Dsolr.solr.home=instance2 -Djetty.port=8502 
-Djetty.home=$SOLR_HOME/solrcloud -Dcollection.configName=A01 
-DzkHost=localhost:2181 -jar start.jar
hoping that "-Dcollection.configName=A01" would do what I think it should do :)

But if I then iterate on the "A01" config and bootstrap a new config "A02" 
(stopping all instances of solr first) but don't delete anything from zookeeper:

java -Dsolr.solr.home=instance1 -Djetty.port=8501 
-Djetty.home=$SOLR_HOME/solrcloud 
-Dbootstrap_confdir=$SOLR_HOME/solrcloud/instance1/core0/conf 
-Dcollection.configName=A02 -DnumShards=2 -DzkHost=localhost:2181 -jar start.jar
I see it upload the configs:

Aug 16, 2012 1:05:47 PM org.apache.solr.common.cloud.SolrZkClient makePathINFO: 
makePath: /configs/A02/admin-extra.htmlAug 16, 2012 1:05:47 PM 
org.apache.solr.common.cloud.SolrZkClient makePathINFO: makePath: 
/configs/A02/admin-extra.menu-bottom.html
...
...so I had hoped it would use the given one in configName.  Things seem to run 
fine, but then if I do delete something from A01 to prove that it's using the 
new config, I start to see error messages about things missing from A01 ... 
showing me it's still using the old config:

(delete /configs/A01/admin-extra.html in zkCli)Aug 16, 2012 2:04:01 PM 
org.apache.solr.common.SolrException logSEVERE: 
org.apache.solr.common.SolrException: Can not find: 
/configs/A01/admin-extra.htmlat 
org.apache.solr.handler.admin.ShowFileRequestHandler.showFromZooKeeper(ShowFileRequestHandler.java:155)
  at 
org.apache.solr.handler.admin.ShowFileRequestHandler.handleRequestBody(ShowFileRequestHandler.java:120)on
 the console running instance1

I'm sure I'm just missing something simple here, but I didn't see any reference 
online about re-bootstrapping.  I also tried this adding -Dbootstrap_conf=true 
[1] to each but that didn't make a difference.

How to implement Index time boost via DIH?

[bbarani]

Hi,

I am trying to implement index time boost via DIH. but I want to boost at
field level rather than document level. Ex:

Consider there are 2 fields in a document: LastUpdatedBy, fullName. After
indexing both the fields, I am copying the data from both the field in to a
default search field. Now when search happens on default search field I want
fullNameto get more priority than LastUpdatedBy even though both might have
the search keyword. 

Note: I have tried dismax handler before for runtime boosting, want to try
index time boosing using DIH.

Thanks!!!

Thanks,
BB

Re: solrcloud/solr4: how to specify a new configuration to use, superseding previous configs w/o deleting‏

[Mark Miller]

Check out some of the new documentation I added today: 
http://wiki.apache.org/solr/SolrCloud/#Command_Line_Util

Collections link with config sets following these rules:

1. When a collection starts, if there is only one config set, the collection 
will link to it. 

2. If a collection starts and it shares the name of a config set, it will link 
to it. 

3. Otherwise, the link has to be created manually - or by specifying it 
explicitly when creating the collection by HTTP API.

boostrap_conf=true uploads a conf set for each core in solr.xml - and it links 
the conf sets to the collections by creating conf set names that match the 
collection names.

If a collection has been linked to a config set, you have to manually update it 
to link it to a new config.

You can do this with the above Command Line Util tool - one of the commands 
links collections to config sets.

You can even make the links before starting Solr for the first time - when you 
do start Solr, as collections are started, it will find and use the link info 
you have created with the tool when names match.

If you change the link while Solr is running you would want to reload all the 
cores in your collection to pick up the new config - you can do this with the 
Collections API: 
http://wiki.apache.org/solr/SolrCloud/#Managing_collections_via_the_Collections_API

Re: solrcloud/solr4: how to specify a new configuration to use, superseding previous configs w/o deleting‏

[Mark Miller]

Another clarification: -Dbootstrap_confdir=./solr/collection1/conf 
-Dcollection.configName=myconf creates no actual link. It simply uploads a 
config set from a dir and calls it myconf. In the example we count on the rule 
of, if there is only one config set a new collection will be linked to it.

splitOnCaseChange not working?

[vod]

Hi,

I'm getting unexpected results and hoping someone can help. My schema.xml
has splitOnCaseChange="1" for the field I'm searching on (both index &
query), and the default search behavior is "OR".

I have a field with the word "Airline" indexed. When i search for "Airline"
I get the match. When I search for "Airline Alias", I get the match (as
expected). However, when I search for "AirlineAlias", I am not getting a
match. I was expecting the splitOnCaseChange property to separate out the
term AirlineAlias into the 2 base words. However, if that was happening,
then it should be finding the match to "Airline" (i.e. it should be the
exact same query as "Airline Alias").

Is my understanding correct? If so, any ideas on why I would not be getting
the correct search results?

I have copied the relevant sections from the schema.xml file below.

Thanks in advance for the help.

Re: Running out of memory

[Amit Nithian]

I am debugging an out of memory error myself and a few suggestions:
1) Are you looking at your search logs around the time of the memory
error? In my case, I found a few bad queries requesting a ton of rows
(basically the whole index's worth which I think is an error somewhere
in our app just have to find it) which happened close to the OOM error
being thrown.
2) Do you have Solr hooked up to something like NewRelic/AppDynamics
to see the cache usage in real time? Maybe as was suggested, tuning
down or eliminating low used caches could help.
3) Are you ensuring that you aren't setting "stored=true" on fields
that don't need it? This will increase the index size and possibly the
cache size if lazy loading isn't enabled (to be honest, this part I am
a bit unclear of since I haven't had much experience with this
myself).

Thanks
Amit

Re: splitOnCaseChange not working?

[Jack Krupansky]

Just set autoGeneratePhraseQueries="false" on the ="text_en_splitting" field 
type.


The current setting treated AirlineAlias as the quoted phrase "Airline 
Alias".

RE: Solr4.0 BETA - Error when StempelPolishStemFilterFactory

Hi sausarkar,

You've probably been hit by the local configuration equivalent of 
 - the Solr example 
configuration directory added a path segment, so  references have to be 
changed to include an extra "../".

Re: MySQL Exception: Communications link failure WITH DataImportHandler

[Alexey Serba]

My memory is vague, but I think I've seen something similar with older
versions of Solr.

Is it possible that you have significant database import and there's a
big segments merge happening in the middle causing blocking in dih
indexing process (and reading records from database as well), since
long inactivity in communication with db server and timeout as a
result. If this is the case then you can either increase timeout limit
on db server (don't remember the actual parameter) or upgrade Solr to
newer version that doesn't have such long pauses (4.0 beta?).

Correct. And you can even use that location index/collection for
locations extraction for a non structural documents - i.e. if you
don't have separate field with geographical names in your corpus (or
location data is just not good enough compared to what can be mined
from documents)

Yes, you can add postcode/outcodes there also. And I would add
additional field "type" region/county/town/postcode/outcode.

Yeah, you might want to boost cities more than towns (I'm sure there
are plenty ambiguous terms), use some kind of geoip service,
additional scoring factors.

You can also have special logic to decide if you want to use spatial
search or just simple textual match would be better. I.e. you have
"England" in your example. It doesn't sound practical to return
coordinates and use spatial search for this use case, right?

HTH,
Alexey

When does this error happen? Immediately upon connection,
or randomly at some point of time. If the former, double
check your mysql configuration string.

With Solr 1.4, we occasionally saw DIH connection failures
to the database, but those were rare, probably attributable
to network issues, and largely went away when:
  (a) We first moved to a different JDBC driver
  (b) Moved from SQL server to mysql.
Is it possible that there are network issues between your live
Solr and the database server? Are you monitoring the load
on the database server, and the volume of network traffic?

Gora

Re: SOLR3.6:Field Collapsing/Grouping throws OOM

Awesome, you rock !!!. Thanks to Eric too for coming up with the ideas. But 
honestly I am more interested to know this EFF concept. I will do my reading 
and then throw up questions if I don't get it. 

External File Field and function queries are something which i have not 
evaluated yet, but I am not too sure if they all will work in scale set ups 
with millions of objects inside SOLR.

Re: MySQL Exception: Communications link failure WITH DataImportHandler

[Jienan Duan]

It happens immediately upon connection,the jdbc string is correct.
This problem only happens when DIH trying get a connection to mysql,the
network and database server are fine.
So I guess it caused by some security configuration on the server and that
config has blocked the connection.
But other app's jdbc connection and Tomcat's JNDI datasource are
insusceptible.
PS: I use Solr 3.5
