Creating Solr servers dynamically in Multicore folder
Hello , I am using solr 4.8.1 Version and and i am trying to create the cores dynamically on server start up using the following piece of code. HttpSolrServer s = new HttpSolrServer( url ); s.setParser(new BinaryResponseParser()); s.setRequestWriter(new BinaryRequestWriter()); SolrServer server = s; String instanceDir =/opt/solr/core/multicore/; CoreAdminResponse e = new CoreAdminRequest().createCore(name, instanceDir, server,/opt/solr/core/multicore/solrconfig.xml,/opt/solr/core/multicore/schema.xml); I am getting the error org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Error CREA TEing SolrCore 'hellocore': Could not create a new core in /opt/solr/core/multic ore/as another core is already defined there at org.apache.solr.client.solrj.impl.HttpSolrServer.executeMethod(HttpSo lrServer.java:554) at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServ er.java:210) at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServ er.java:206) at org.apache.solr.client.solrj.request.CoreAdminRequest.process(CoreAdm inRequest.java:503) at org.apache.solr.client.solrj.request.CoreAdminRequest.createCore(Core AdminRequest.java:580) at org.apache.solr.client.solrj.request.CoreAdminRequest.createCore(Core AdminRequest.java:560) at app.services.OperativeAdminScheduler.scheduleTask(OperativeAdminSched uler.java:154) at Global.onStart(Global.java:31) I am still getting the above error even though the core0 and core1 folders in multicore are deleted and the same is commented in /opt/solr/core/multicore/solrconfig.xml.

SOLR tuning
Hi,
Newbie testing on laptop here. I've got two cores (shards) in my datastore.
When searching I get this error if result is above approx. 200'000 records,
below 200'000 it returns fine. I thought it was simply a case of upping Java
heap size, but no luck. I do not want to use start/cursorMark in this case,
anyone know what to tune exactly in order to get more than 200'000 records
back? Running in JBOSS.
Thanks!

Chronological partitioning of data - what does Solr offer in this area?
Hello! *Does Solr support any sort of chronological ordering of data?* I would like to divide my data to: Daily, weekly, monthly, yearly parts. For performance sake. Has anyone done something like this over SolrCloud? More thoughts: While Indexing: I'm soft committing every 2 seconds so I would rather do that on the daily index only (open reader and cache invalidation effort) as the total index shard size is 200GB While Searching: I would rather search first the daily and weekly parts, moving to older data only if results are not satisfying. I guess there's a challenge to move the daily data to the weekly data at the end of a day, and so on Anything build-in that goes in this direction? If not, any example of some custom collection/sharding configuration? Thanks. Gili.
Sorting docs by Hamming distance

When searching for doc_hash:123456780 the sort order should be - doc1,doc2. What would be the best way to achieve this kind of behaviour? Writing a plugin or maybe a custom function query ?

Re: Master - Master / Upgrading a slave to master

So can we just have nodes for redundancy and NOT load balancing i.e. it has 3 nodes but update is only on one of them?

As someone else already said, you can write a custom request handler and reference it in a handler definition in your solrconfig.xml file. The sky's the limit for that -- if you can write the code, Solr will use it. This *specific* example that you've given is something that the edismax parser will give you out of the box, when you define the qf and pf parameters. It will automatically search the individual terms you give on the fields in the qf parameter, *and* do a phrase search for all those terms on the fields in the pf parameter. https://cwiki.apache.org/confluence/display/solr/The+Extended+DisMax+Query+Parser http://wiki.apache.org/solr/ExtendedDisMax Thanks, Shawn

Re: Master - Master / Upgrading a slave to master
So realistically speaking you cannot have SolrCloud work for 2 data centers as a redundant solution because no matter how many nodes you add you still would need at least 1 node in the 2nd center working too. So that just leaves with non-SolrCloud solutions. 1) Change the replication config to redefine the master and reload the core or restart Solr. That of course is a simple way but the real issue is about the possible issues and some good practices e.g. normally the scenario would be that primary data center goes down for few hours and till then we upgrade one of the slaves in secondary to a master. Now - IF there is no lag there won't be any issue in secondary at least but what if there is lag and one of the files is not completely replicated? That file would be discarded or there is a possibility that whole index is not usable? - Once the primary comes back how would we now copy the delta from secondary? Make it a slave of secondary first, replicate the delta and then set it as a master again? In other words is there a good guide out there for this with possible issues and solutions? Definitely before SolrCloud people would be doing this and even now SolrCloud doesn't seem practical in quite a few situations. Thanks again!!

[Announce] Apache Solr 4.10 with RankingAlgorithm 1.5.4 available now with complex-lsa algorithm (simulates human language acquisition and recognition)
Hi! I am very excited to announce the availability of Apache Solr 4.10 with RankingAlgorithm 1.5.4. Solr 4.10.0 with RankingAlgorithm 1.5.4 includes support for complex-lsa. complex-lsa simulates human language acquisition and recognition (see demo http://solr-ra.tgels.org/rankingsearchlsa.jsp ) and can retrieve semantically related/hidden relationships between terms, sentences, paragraphs, chapters, books, images, etc. Three new similarities, TERM_SIMILARITY, DOCUMENT_SIMILARITY, TERM_DOCUMENT_SIMILARITY enable these with improved precision. A query for holy AND ghost returns jesus/christ as the top results for the bible corpus with no effort to introduce this relationship (see demo http://solr-ra.tgels.org/rankingsearchlsa.jsp ). This version adds support for multiple linear algebra libraries. complex-lsa does a large amount of this calcs so speeding this up should speed up the retrieval etc. EJML is the fastest if you are using complex-lsa for a smaller set of documents, while MTJ is faster as your document collection becomes bigger. MTJ can also use BLAS/LAPACK, etc installed on your system to further improve performance with native execution. The performance is similar to a C/C++ application. It can also make use of GPUs or Intel's mkl library if you have access to it.

Re: Using a RequestHandler to expand query parameter
So, the problem I found that's driving this is that I have several phrase synonyms set up. For example, ipod mini into ipad mini. This synonym is only applied if you submit it as a phrase in quotes. So, the pf param doesn't help because it's not the right phrase in the first place. I can fix this by sending in the query as (ipod mini ipod mini). -- View this message in context: http://lucene.472066.n3.nabble.com/Using-a-RequestHandler-to-expand-query-parameter-tp4155596p4157637.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: Solr Sharding Help
Thanks Jeff. I had different idea of how replicationFactor worked. I was able to create the setup with that command. Now as I import data into the cluster how can I determine that it's being sharding?

Solr doesn¹t ³auto fill² available capacity, contrary to the misleading examples on the http://wiki.apache.org/solr/SolrCloud page.

Re: [Announce] Apache Solr 4.10 with RankingAlgorithm 1.5.4 available now with complex-lsa algorithm (simulates human language acquisition and recognition)
Interesting. Does anyone know how that compares to this http://www.searchbox.com/products/searchbox-plugins/solr-sense/? Diego Fernandez - 爱国 Software Engineer US GSS Supportability - Diagnostics - Original Message - Hi! I am very excited to announce the availability of Apache Solr 4.10 with RankingAlgorithm 1.5.4. Solr 4.10.0 with RankingAlgorithm 1.5.4 includes support for complex-lsa. complex-lsa simulates human language acquisition and recognition (see demo http://solr-ra.tgels.org/rankingsearchlsa.jsp ) and can retrieve semantically related/hidden relationships between terms, sentences, paragraphs, chapters, books, images, etc. Three new similarities, TERM_SIMILARITY, DOCUMENT_SIMILARITY, TERM_DOCUMENT_SIMILARITY enable these with improved precision. A query for “holy AND ghost” returns jesus/christ as the top results for the bible corpus with no effort to introduce this relationship (see demo http://solr-ra.tgels.org/rankingsearchlsa.jsp ). This version adds support for multiple linear algebra libraries. complex-lsa does a large amount of this calcs so speeding this up should speed up the retrieval etc. EJML is the fastest if you are using complex-lsa for a smaller set of documents, while MTJ is faster as your document collection becomes bigger. MTJ can also use BLAS/LAPACK, etc installed on your system to further improve performance with native execution. The performance is similar to a C/C++ application. It can also make use of GPUs or Intel's mkl library if you have access to it.

Re: ExtractingRequestHandler indexing zip files
I am also having the issue where my zip contents (or kmz contents) are not

The patch you mention has been around for a while. I am running solr 4.8.1

included already. Do I need additional configuration? My config is as
follows:

transformer=TemplateTransformer url=${kmlfiles.fileAbsolutePath}
more field defs
//entity
/entity
/document/dataConfig
and I am using the dataImport option from the admin page Thanks for any
assistance - I'm on a closed network and getting patches to it are not
trival.

Re: Creating Solr servers dynamically in Multicore folder
Well, you already have a core.properties file defined in that location. I presume you're operating in core discovery mode. Your cores would all be very confused if new cores were defined over top of old cores. It is a little clumsy at this point in that you have to have a conf directory in place but _not_ a core.properties file to create a core like this. Config sets will eventually fix this.

Re: Using def function in fl criteria,

intend the syntax

It's also really difficult to say much of anything unless we see the

Likely you're somehow applying an analysis chain that is truncating
the input. Or it's also possible that you aren't indexing quite what

Czech stemmer
Hi, I'm facing stemming issues with the Czech language search. Solr/Lucene currently provides CzechStemFilterFactory as the sole option. Snowball Porter doesn't seem to be available for Czech. Here's the issue. I'm trying to search for posunout (means move in English) which returns result, but fails if I use ''posunulo (means moved in English). I used the following text as field for search. Pomocí multifunkčních uzlů je možné odkazy mnoha způsoby upravovat.

Wildcard in FL parameter not working with Solr 4.10.0
Hello,
With Solr 4.7 we had some queries that return dynamic fields by passing in
a fl=*_exact parameter; this is not working for us after upgrading to Solr
4.10.0. This appears to only be a problem when requesting wildcarded
fields via SolrJ
With Solr 4.10.0 - I downloaded the binary and set up the example:
cd example
java -jar start.jar
java -jar post.jar solr.xml monitor.xml
In a browser, if I request
http://localhost:8983/solr/collection1/select?q=*:*wt=jsonindent=true
*fl=*d*
All is well with the world:
{responseHeader: {status: 0,QTime: 1,params: {fl: *d,indent:
true,q: *:*,wt: json}},response: {numFound: 2,start: 0,docs
: [{id: SOLR1000},{id: 3007WFP}]}}
However if I do the same query with SolrJ (groovy script)
@Grab(group = 'org.apache.solr', module = 'solr-solrj', version = '4.10.0')
import org.apache.solr.client.solrj.SolrQuery
import org.apache.solr.client.solrj.impl.HttpSolrServer
HttpSolrServer solrServer = new HttpSolrServer(
http://localhost:8983/solr/collection1;)
SolrQuery q = new SolrQuery(*:*)
*q.setFields(*d)*
println solrServer.query(q)
No fields are returned:
{responseHeader={status=0,QTime=0,params={fl=*d,q=*:*,wt=javabin,version=2}},response={numFound=2,start=0,docs=[*SolrDocument{},
SolrDocument{}*]}}
Any ideas as to why when using SolrJ wildcarded fl fields are not returned?
Thanks,
Mike
Re: How to implement multilingual word components fields schema?
Ilia, one aspect you surely loose with a single field approach is the differentiation of semantic fields in different languages for words that sounds the same. The words sitting and directions are easy example that have fully different semantics in French and English, at least. directions would appear common with, say, teacher advice in English but not in French. I disagree that the storage should be an issue in your case…. most solr installations do not suffer from that, as far as I can read the list. Generally, you do not need all these stemmed fields to be stored, they're just indexed and that is pretty tiny a storage. Using separate fields also has advantages in terms of IDF, I think. I do not understand the last question to Tom, he provides URLs to at least one of the papers. Also, if you can put a hand on it, the book of Peters, Braschler, and Clough is probably relevant: http://link.springer.com/book/10.1007%2F978-3-642-23008-0 but, as the first article referenced by Tom says, the CLIR approach here relies on parallel corpora, e.g. created by automatic translations. Paul On 8 sept. 2014, at 07:33, Ilia Sretenskii sreten...@multivi.ru wrote: Thank you for the replies, guys! Using field-per-language approach for multilingual content is the last thing I would try since my actual task is to implement a search functionality which would implement relatively the same possibilities for every known world language. The closest references are those popular web search engines, they seem to serve worldwide users with their different languages and even cross-language queries as well. Thus, a field-per-language approach would be a sure waste of storage resources due to the high number of duplicates, since there are over 200 known languages. I really would like to keep single field for cross-language searchable text content, witout splitting it into specific language fields or specific language cores. So my current choice will be to stay with just the ICUTokenizer and ICUFoldingFilter as they are without any language specific stemmers/lemmatizers yet at all. Probably I will put the most popular languages stop words filters and stemmers into the same one searchable text field to give it a try and see if it works correctly in a stack. Does specific language related filters stacking work correctly in one field? Further development will most likely involve some advanced custom analyzers like the SimplePolyGlotStemmingTokenFilter to utilize the ICU generated ScriptAttribute. http://comments.gmane.org/gmane.comp.jakarta.lucene.solr.user/100236 https://github.com/whateverdood/cross-lingual-search/blob/master/src/main/java/org/apache/lucene/sandbox/analysis/polyglot/SimplePolyGlotStemmingTokenFilter.java So I would like to know more about those academic papers on this issue of how best to deal with mixed language/mixed script queries and documents.
