> Trying to use SnowballPorterFilterFactory in  @AnalyzerDef will currently throw the following exception:
> java.lang.NoClassDefFoundError: org/apache/solr/request/QueryResponseWriter
> 	at org.apache.solr.analysis.SnowballPorterFilterFactory.init(SnowballPorterFilterFactory.java:42)
> The problem is SnowballPorterFilterFactory contains a log statement using SolrCore.log.fine(). SolrCore itself has then a whole list of other import statements including QueryResponseWriter. Within Hibernate Search we use a custom/shrinked version of the solr jar which only contains the classes needed for analysis. QueryResponseWriter should of course not be required (see http://repository.jboss.org/maven2/org/hibernate/apache/lucene/solr/apache-solr-analyzer/1.2.0/solrshrinker-build.xml).
> The problem does not occur when the full solr jar is used.
> We need to start a discussion with the solr developers regrading this logging issue.
> Example annotation causing the error:
> @AnalyzerDef(name="customanalyzer",
> 		tokenizer = @TokenizerDef(factory = StandardTokenizerFactory.class),
> 		filters = {
> 				@TokenFilterDef(factory = LowerCaseFilterFactory.class),
> 				@TokenFilterDef(factory = SnowballPorterFilterFactory.class,params = {
> 					@Parameter(name="language", value= "English")
> 				}),
> })
