> 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.
