Oh you are constructing the string 'fly +body:away' in your StemFilter? Just to make sure, does this q=+body:(fly away) return your document? And analysis.jsp (at query time) displays 'fly +body:away' from the string 'flyaway'?
I don't know why are you doing this but your stemfilter should return only terms, not field names attached to it. Maybe you can find this useful so that you can do what you want without writing custom code. http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.SynonymFilterFactory --- On Tue, 10/19/10, Jerad <ag...@naver.com> wrote: > From: Jerad <ag...@naver.com> > Subject: Re: How can i get collect stemmed query? > To: solr-user@lucene.apache.org > Date: Tuesday, October 19, 2010, 5:10 AM > > Thanks for your reply :) > > 1.
