Re: Odd Boolean Query behavior in SOLR 3.6

Inner purely negative queries match nothing. A query is about matching, and skipping over things that don’t match. The fix is when using (-something) to do (*:* -something) to match everything and skip the negative clause items. In your example, try fq=((*:* -documentTypeId:3) AND companyId:29

Just a thought - this looks like it could be due to the regexp (/pattern/ syntax) support added, but that was added in Lucene 4.0 so it doesn't quite fit that it would be a difference between 4.1 and 4.2.1. Erik On May 19, 2013, at 14:50 , Scott Smith wrote: > I just upgraded from lu

PhraseQuery suffices for the stated requirement of boosting when query terms are closer. A common technique is to incorporate a PhraseQuery with a large slop factor of the query terms into the query automatically, which implicitly boosts matching documents when the query terms are closer. A Sp
