Description
The Stempel stemmer appears to be broken under Solr in v4.0.0-BETA, very likely related to LUCENE-2510 / LUCENE-4044.
When I add the following to the example, I get the below-listed exception on start-up:
solrconfig.xml
<lib dir="../../../contrib/analysis-extras/lucene-libs/" regex=".*\.jar"/>
schema.xml
<fields> <field name="content" type="text_pl" indexed="true" stored="false" multiValued="true"/> [...] <types> <fieldType name="text_pl" class="solr.TextField" positionIncrementGap="100"> <analyzer> <tokenizer class="solr.StandardTokenizerFactory"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.StempelPolishStemFilterFactory"/> </analyzer> </fieldType>
Solr console output
[...]
