I didn't mention it but I'd like individual fields to contribute to the overall score on a continuum instead of 1 (match) and 0 (no match), which will lead to more fine-grained scoring.
A contrived example: all other things equal a tv of 40 inch should score higher than a 38 inch tv when searching for a 42 inch tv. This based on some distance modeling on the 'size' -field. (eg: score(42,40) = 0.6 and score(42,38) = 0,4). Other qualitative fields may be modeled in the same way: (e.g: restaurants with field 'price' with values: 'budget','mid-range', 'expensive', ...) Any way to incorporate this? 2013/5/9 Jack Krupansky <j...@basetechnology.com> > A simple "OR" boolean query will boost documents that have more matches. > You can also selectively boost individual OR terms to control importance. > And do and "AND" for the required terms, like "tv". > > -- Jack Krupansky > -----Original Message----- From: britske > Sent: Thursday, May 09, 2013 11:21 AM > To: solr-user@lucene.apache.org > Subject: Fuzzy searching documents over multiple fields using Solr > > > Not sure if this has ever come up (or perhaps even implemented without me > knowing) , but I'm interested in doing Fuzzy search over multiple fields > using Solr. > > What I mean is the ability to returns documents based on some 'distance > calculation' without documents having to match 100% to the query. > > Usecase: a user is searching for a tv with a couple of filters selected.
