I've been thinking about the CommonGramsFilter for a while, and am confused about how it works. Can anyone provide examples? Are you meant to include the analyzer at both index and query time? The description on the wiki says among other things: "The CommonGramsQueryFilter converts the phrase query "the cat" into the single term query the_cat." -- does that mean it _only_ works on phrase queries? If you've indexed with commongrams, what will happen at query time to a non-phrase query <<the cat>> ? Very confused. ________________________________________ From: Steven A Rowe [sar...@syr.edu] Sent: Thursday, September 23, 2010 8:21 AM To: solr-user@lucene.apache.org Subject: RE: bi-grams for common terms - any analyzers do that?
