Thanks Nagendra.

But I wasn't talking about field boost. The kind of boosting I need:

{!boost b=log(popularity)}foo

requires BoostQParserPlugin 
(http://search-lucene.com/jd/solr/org/apache/solr/search/BoostQParserPlugin.html
 )

Does Solr-RA come with BoostQParserPlugin?

Thanks.

The Replication feature does this. If you configure a query server as
a 'backup' server, it downloads changes but does not read them.

Re: updates not reflected in solr admin

Right I read those comments in the config, and it all sounds reasonable 
- presumably a new Searcher is opened when (or shortly after) we commit, 
from whatever source.  That was my operating assumption, and the reason 
I was so confused when I saw different result in two different clients.  
I don't want to pursue this probable user error beyond eliminating the 
obvious for the moment.  I'll post back if I get more info.  Thanks

Re: How to debug if termsComponent is used

[Otis Gospodnetic]

Hi,

That looks about right, but I don't know without checking around if debug 
component really needs query component, or if it can work with just terms 
component.
Have you tried it?  Did it not work?

You may save yourself a lot of work and get something better than terms 
component with http://sematext.com/products/autocomplete/index.html btw.  Or if 
you are using Solr trunk, with Suggester.

Everything should work as before. So faceting, function queries, query

Hi Andy:

I have a solution for NRT with Solr 1.4.1. The solution
uses the RankingAlgorithm as the search library. The NRT
functionality allows you to add documents without the
IndexSearchers being closed or caches being cleared. A
commit is not needed with the document update. Searches can
run concurrently with document updates. No changes are
needed except for enabling the NRT through solrconfig.xml.
The performance is about  262 TPS (document adds) on a
dual core intel system with 2GB heap with searches in
parallel. The performance at the moment is limited by how
fast IndexWriter.getReader() performs.

I have a white paper that describes NRT in details, allows
you to download the tweets, schema and solrconfig.xml files.
You can access the white paper from here:

http://solr-ra.tgels.com/papers/solr-ra_real_time_search.pdf

You can download Solr with RankingAlgorithm (Solr-RA) from
here:

http://solr-ra.tgels.com

I still have not yet integrated the NRT with Solr 3.1 (the
new release) and plan to do so very soon.

Please let me know if you need any more info.

Re: Dismax Minimum Match/Stopwords Bug

[Chris Hostetter]

: However, is there an actual fix in the 3.1 eDisMax parser which solves 
: the problem for real? Cannot find a JIRA issue for it.

edismax uses the same query structure as dismax, which means it's not 
possible to "fix" anything here ... it's how the query parsers work.

each "word" from the query string is analyzed by each field in the "qf", 
and the result is used as a query on the "word" in the field.  The 
individual clauses for each word are aggregated into a 
DisjunctionMaxQuery, and the set of DisjunctionMaxQueries are then 
combined into a BooleanQuery (with the appropriate minNrShouldMatch set)

if a "word" from the input produces no output from the analyzers of *any* 
of the of fields, then the resulting DisjunctionMaxQuery is empty and 
droped from the final BooleanQuery ... so if a "word" in the query string 
is stop word for *every* field in the qf, there is no clause.  but if 
*any* field in the qf produces a term for it, then there is a 
DisjunctionMaxQuery for that word added to hte main BooleanQuery.

As i've said many times: this isn't a bug, it's fundemental point of the 
parser and the structure of the query.

The best "solution" for people who get bit by this (in my opinion) is not 
to give up on stop words -- if you want to use stop words, by all means 
use stop words.  BUT! You must use them in all the fields of your qf ... 
evne fields where you think "why in gods name would i need stopwords on 
this field, those terms will never exist in this field!" ... you may know 
that, and it may be true, but it doesn't change the fact that people will 
be *querying* for stop words against those fields, and you want to ignore 
them when they do.

That sounds quite reasonable indeed. But i don't understand why Solr doesn't 
throw an exception when i actually index a string in a long fieldType while i 
do remember getting some number formatting exception when pushing strings to 
an integer fieldType.

With the current set up i can send a properly formatted date to a long 
fieldType, which should, in my opionion, punish me with an exception.

[Chris Hostetter]

: Any thoughts on this one? Why does Solr output a string in a long field with

performance.

the XML Response writer doesn't make any attempt to validate data from 
the index on the way out, the stored value in the index is a string, and 
the stream it's writing to accepts strings, so it writes the value as a 
string wrapped in  tags.

The Binary response writer on the other hand streams strings differnetly 
then longs, so it does care when it encounters the inforrect type, and it 
errors.

Bottom line: if your schema.xml is not consistent with your index, all 
bets are off as to what the behavior will be.

Indexing multiple languages

multilanguage, I need to index them in multiple languages.

My table looks like this:

id  int Unchecked
title   nvarchar(50)Unchecked
title_ennvarchar(50)Unchecked
title_nlnvarchar(50)Unchecked




In my data-config.xml I have this, only for 1 language:








Now, the only way I can imagine indexing multiple languages is by
duplicating these lines:














Is there a better way, e.g. where I can do some sort of parametering like
{lang] or something?

Re: fq parameter with partial value

[Jonathan Rochkind]

So if you have a field that IS tokenized, regardless of what it's 
called, then when you send "My Great Restaurant" to it for _indexing_, 
it gets _tokenized upon indexing_ to seperate tokens:  "My", "Great", 
"Restaurant".  Depending on what other analysis you have, it may get 
further analyzed, perhaps to: "my", "great", "restaurant".


You don't need to seperate into tokens yourself before sending it to 
Solr for indexing, if you define the field using a tokenizer, Solr will 
do that when you index.  Because this is a VERY common thing to do with 
Solr; pretty much any field that you want to be effectively searchable 
you have Solr tokenize like this.


Because Solr pretty much always matches on individual tokens, that's the 
fundamental way Solr works.
Those seperate tokens is what allows you to SEARCH on the field, and get 
a match on "my" or on "restaurant".   If the field were non-tokenized, 
you'd ONLY get a hit if the user entered "My Great Restaurant" (and 
really not even then unless you take other actions, because of the way 
Solr query parsers work you'll have trouble getting ANY hits to a 
user-entered search with the 'lucene' or 'dismax' query parsers if you 
don't tokenize).


That tokenized filed won't facet very well though -- if you facetted on 
a tokenized field with that example entered in it, you'll get a facet 
"my" with that item in it, and another facet "great" with that item in 
it, and another facet "restuarant" with that item in it.


Which is why you likely want to use a seperate _untokenized_ field for 
facetting. Which is why you end up wanting/needing two seperate fields 
-- one that is tokenized for searching, and one that is not tokenized 
(and usually not analyzed at all) for facetting.


Hope this helps.

You could have this be a multiValued field with an increment gap if you

Re: DataImportHandler on 2 tables

[lboutros]

Do you want to search on the datas from the tables together or seperately ?
Is there a join between the two tables ?

DataImportHandler on 2 tables

[Greg Georges]

Hello all,

I have a system where I have a dataimporthandler defined for one table in my 
database. I need to also index data from another table, so therefore I will 
need another index to search on. Does this mean I must configure another solr 
instance (another schema.xml file, dataimporthandler sql file, etc)? Do I need 
another solr core for this? Thanks

RE: Question concerning the updating of my solr index

[Greg Georges]

Yeah you are right, I have changed that to add a document and not a list of 
documents. Still works pretty fast, I will continue to test settings to see if 
I can tweak it further. Thanks

Greg,

I believe the point of SUSS is that you can just add docs to it one by one, so 
that SUSS can asynchronously send them to the backend Solr instead of you 
batching the docs.

Re: Why are they different?

[Chris Hostetter]

: The above code, if I start the server(tomcat) inside eclipse, it throws 
: "SolrException : Internal Server Error"; but if I start the server 
: outside eclipse, for instance, run "startup.bat" in tomcat's bin 
: directory, it runs successfully. I really don't understand Why they are 
: different.

Have you checked the logs?

My guess is that when you use eclipse, the server is not starting up 
properly at all.  Possible not finding the Solr Home directory?

Re: when to change rows param?

[Chris Hostetter]

: I thought that injecting the rows param in the query-component would 
: have been enough (from the "limits" param my client is giving). But it 
: seems not to be the case.

As i tried to explain before: the details matter.  exactly where in the 
code you tried to do this and how you went about it is important to 
understanding why it might not have affected the results in the way you 
expect.

SearchComponents are ordered, and multiple passes are made over each 
component in order, and each component has the opportunity to access the 
request params in a variety of ways, etc...

So w/o knowing exactly what you changed, we can't really speculate why 
some other code isn't using the new value (particularly since i don't 
think you ever actaully told use *which* other code isn't getting the new 
value)

Greg,

You could use StreamingUpdateSolrServer instead of that UpdateRequest class - 
http://search-lucene.com/?q=StreamingUpdateSolrServer+&fc_project=Solr
Your index won't be locked in the sense that you could have multiple apps or 
threads adding docs to the same index simultaneously and that searches can be

Re: Too many open files exception related to solrj getServer too often?

[Chris Hostetter]

Off the top of my head, i don't know hte answers to some of your 
questions, but as to the core cause of the exception...

: 3. server.query(solrQuery) throws SolrServerException.  How can concurrent
: solr queries triggers Too many open file exception?

...bear in mind that (as i understand it) the limit on open files is 
actually a limit on open file *descriptors* which includes network 
sockets.

a google search for "java.net.SocketException: Too many open files" will 
give you loads of results -- it's not specific to solr.

Re: How to combine Deduplication and Elevation

: Hi I have a question. How to combine the Deduplication and Elevation
: implementations in Solr. Currently , I managed to implement either one only.

can you elaborate a bit more on what exactly you've tried and what problem 
you are facing?

the SignatureUpdateProcessorFactory (which is used for Deduplication) and 
the QueryElevation component should work just fine together -- in fact: 
one is used at index time and hte ohter at query time, so where shouldn't 
be any interaction at all...

Yes separate commit is needed.
   

Re: querying in Java

[Anuj Kumar]

Hi Jeff,

Either you can use a filter query or specify it explicitly,
like- "Field:Value OR color:blue OR dayOfWeek:Tuesday"
or use AND in between. It depends on what you want.

Also, if you don't want to specify AND/OR and decide on a global
declaration, then set it as the default operator in your schema.xml. For
example-

 

Hope it helps.

Anuj

Re: Question concerning the updating of my solr index

[Otis Gospodnetic]

Greg,

You could use StreamingUpdateSolrServer instead of that UpdateRequest class - 
http://search-lucene.com/?q=StreamingUpdateSolrServer+&fc_project=Solr
Your index won't be locked in the sense that you could have multiple apps or 
threads adding docs to the same index simultaneously and that searches can be 
executed against the index concurrently.

Question concerning the updating of my solr index

[Greg Georges]

Hello all,

I have integrated Solr into my project with success. I use a dataimporthandler 
to first import the data mapping the fields to my schema.xml. I use Solrj to 
query the data and also use faceting. Works great.

The question I have now is a general one on updating the index and how it 
works. Right now, I have a thread which runs a couple of times a day to update 
the index. My index is composed of about 2 documents, and when this thread 
is run it takes the data of the 2 documents in the db, I create a 
solrdocument for each and I then use this line of code to index the index.

SolrServer server = new 
CommonsHttpSolrServer("http://localhost:8080/apache-solr-1.4.1/";);
Collection docs = new ArrayList();

for (Iterator iterator = documents.iterator(); iterator.hasNext();) {
Document document = (Document) iterator.next();
SolrInputDocument solrDoc = SolrUtils.createDocsSolrDocument(document);
   docs.add(solrDoc);
}

UpdateRequest req = new UpdateRequest();
req.setAction(UpdateRequest.ACTION.COMMIT, false, false);
req.add(docs);
UpdateResponse rsp = req.process(server);

server.optimize();

This process takes 19 seconds, which is 10 seconds faster than my older 
solution using compass (another opensource search project we used). Is this the 
best was to update the index? If I understand correctly, an update is actually 
a delete in the index then an add. During the 19 seconds, will my index be 
locked only on the document being updated or the whole index could be locked? I 
am not in production yet with this solution, so I want to make sure my update 
process makes sense. Thanks

Greg

RE: querying in Java

This worked.  Thank you.  

What if I want to query for two or more field's values.  For example:
Field  color  dayOf Week

I have tried a query string of "blue&Tuesday", with no success.

Hi Jeff,

In that case, you can create a new index field (set indexed to true and
stored to false) and copy all your fields to it using copyField.
Also make this new field as your default search field.

This will handle your case.

Yes separate commit is needed.

Re: Negative boost

[Ahmet Arslan]

I understand that the only way to simulate a negative boost is to positively
boost the inverse. I have looked at
http://wiki.apache.org/solr/SolrRelevancyFAQ but I think I am missing
something on the formatting of my query. I am using:

http://localhost:8983/solr/search?q=dog&bq=(*:* -species:Sheltie)^1

In this case, I am trying to search for records about "dog" but to put
records containing "Sheltie" closer to the bottom as I am not really
interested in that. However, the following queries:

http://localhost:8983/solr/search?q=dog
http://localhost:8983/solr/search?q=dog&bq=(*:* -species:Sheltie)^1

Return the exact same set of results with a record about a Sheltie as the
top result each time. What am I doing incorrectly?


bq parameter is specific to dismax query parser. 
If you want to benefit from bq, you need to use &defType=dismax as well as 
other dismax's parameters

Re: Highlighting words with non-ascii chars

[Peter Wolanin]

Does your servlet container have the URI encoding set correctly, e.g.
URIEncoding="UTF-8" for tomcat6?

http://wiki.apache.org/solr/SolrTomcat#URI_Charset_Config

Older versions of Jetty use ISO-8859-1 as the default URI encoding,
but jetty 6 should use UTF-8 as default:

updates not reflected in solr admin

[Mike Sokolov]

This is in 1.4 - we push updates via SolrJ; our application sees the 
updates, but when we use the solr admin screens to run test queries, or 
use Luke to view the schema and field values, it sees the database in 
its state prior to the commit.  I think eventually this seems to 
propagate, but I'm not clear how often since we generally restart the 
(tomcat) server in order to get the new commit to be visible.


I saw a comment recently (from Lance) that there is (annoying) HTTP 
caching enabled by default in solrconfig.xml.  Does this sound like 
something that would be caused by that cache?  If so, I'd probably want 
to disable it.   Does that affect performance of queries run via SolrJ?  
Also: why isn't that cache flushed by a commit?  Seems weird...

Your query is going against the default field (defined in schema.xml). Have

What do you have your commit parameters set to in

[EOE] Copyfield is done with the original data, not the processed
data. So it's as though
you added both fields in the input document.

And how can I search only for

[EOE] that's what copyfield does for you.

 And

[EOE] Don't understand your question.

Here's what I'd suggest. Just try it. Then use the admin page to look at
your fields to see what the indexed values are. Also, try using
the admin page to run some test queries with debugging on, I always get
more out of a few experiments than I do out of documentation...

Re: solr sorting problem

[Pratik]

Hi,
Were you able to sort the results using alphaOnlySort ?
If yes what changes were made to the schema and data-config  ? 
Thanks

Re: Bulk update via filter query

[Ahmet Arslan]

Is there an efficient way to update multiple documents with common values
(e.g. color = white)? An example would be to mark all white-colored items as
sold-out.

http://lucene.apache.org/solr/api/org/apache/solr/schema/ExternalFileField.html 
can be an option.

OutOfMemoryError with DIH loading 140.000 documents

[Zoltán Altfatter]

Hi,

I receive OutOfMemoryError with Solr 3.1 when loading around 140.000
document with DIH.
I have set the -Xmx to 1536M. Weird that I cannot give more heap memory.
With -Xmx2G the process doesn't start.

Do you know why can't I set 2G -Xmx to Solr 3.1?

With Solr 4.0 trunk it I don't receive OutOfMemoryError issue, although I
can set the -Xmx to 2G.

Thank you.

Cheers,
Zoltan

Re: solr sorting problem

[Pratik]

Hi, 
Thanks for your reply. 

I'm, using "commit=true" while indexing, and it does index the records and
show the number of records indexed. 
The problem is that search yields 0 records ( numFound="0" ). 

e.g. 
00onappl 

There are some entries for spell checking in my schema too. 
e.g. 

 

The Search URL is something like:- 
http://localhost:8983/solr/select/?q=apple&indent=on 
http://localhost:8983/solr/select/?q=apple&version=2.2&start=0&rows=10&indent=on

Cache could not be a problem as it did not fetch any records from the very
begining. 

So, basically it does not fetch any documents/records whereas it does index
them.

Thanks
Pratik
