Subject [jira] [Created] (SOLR-4251) SynonymFilter fails when provided with optional tokenizerFactory
Date Tue, 01 Jan 2013 01:13:21 GMT
Chris Bleakley created SOLR-4251:
------------------------------------

             Summary: SynonymFilter fails when provided with optional tokenizerFactory
                 Key: SOLR-4251
                 URL: https://issues.apache.org/jira/browse/SOLR-4251
             Project: Solr
          Issue Type: Bug
          Components: Schema and Analysis
    Affects Versions: 4.0, 4.0.1, 4.1, 4.2
            Reporter: Chris Bleakley
            Priority: Minor


Using the solr 4.0 example, if I add an optional tokenizerFactory ( as per http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.SynonymFilterFactory
) to the synonymFilter for the "text_general" field type:

<filter class="solr.SynonymFilterFactory" 
synonyms="synonyms.txt" 
tokenizerFactory="solr.StandardTokenizerFactory" 
ignoreCase="true" 
expand="true"/>

I receive the error at startup:

SEVERE: null:java.lang.IllegalArgumentException: Configuration Error: Factory 'org.apache.lucene.analysis.standard.StandardTokenizerFactory'
needs a 'luceneMatchVersion' parameter

It also fails if I try adding the param luceneMatchVersion="LUCENE_40" :

<filter class="solr.SynonymFilterFactory" 
synonyms="synonyms.txt" 
tokenizerFactory="solr.StandardTokenizerFactory" 
luceneMatchVersion="LUCENE_40"
ignoreCase="true" 
expand="true"/>

----------

It looks like the delegator in the SynonymFilterFactory is not propagating the LUCENE_MATCH_VERSION
to the tokenizer. For tokenizers that don't require a match version (whitespace) everything
works correctly. This issue seems to be a problem in the 4x branch... trunk removes the code
that delegates between the 2 types of synonym filters.
