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.
