Yes, when you change the schema in the indexing portion, it is necessary to reindex the data. You can change the search parts w/o reindexing..
Also, see this page: http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters See the CommonGramsFilterFactory section, which contains this tidibt: <<<CommonGramsFilter is useful for issuing phrase queries (i.e. "the cat") that contain stop words. Normally phrases containing stop words would not match their intended target and instead, the query "the cat" would match all documents containing "cat", which can be undesirable behavior.>> HTH Erick On Fri, Jul 2, 2010 at 11:38 AM, Frederico Azeiteiro < frederico.azeite...@cision.com> wrote: > Thanks Leonardo, I didn't know that tool, very good! > > So I see what is wrong: > > SnowballPorterFilterFactory and StopFilterFactory.
