It is recommended [1] to use synonyms at index time only for various reasons especially with multi-word synonyms.
[1]http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.SynonymFilterFactory only at index time use expand=true ingoreCase=true with synonym.txt : micheal, michael OR: micheal jackson, michael jackson Note it it is important to what filters you have before synonym filter. Bu sure that you restart tomcat and re-index. Query Micheal Jackson (not phrase search) should return the results for Michael Jackson. Hope this helps. --- On Thu, 11/12/09, Nair, Manas <manas.n...@mtvnmix.com> wrote: > From: Nair, Manas <manas.n...@mtvnmix.com> > Subject: Multi word synonym problem > To: solr-user@lucene.apache.org > Cc: "Arumugam, Senthil Kumar" <senthilkumar.arumu...@mtvncontractor.com> > Date: Thursday, November 12, 2009, 3:43 PM > Hi Experts, > > I would like help on multi word synonyms.
