I am not sure if this is supported out of box in Solr. Search by giving multiple facet fields and query containing set of values for each facet field & minimum should match parameter for each facets. The result should be document contains facets with minimum match.
Eg: solr documents of type electronic products. so each document will contain category [lcd,led,plasma], manufacture [sony,samsung, apple] information. query something like http://localhost:8983/solr/select?q=(category:lcd+OR+category:led+OR+category:plasma)+AND+(manufacture:sony+OR+manufacture:samsung+OR+manufacture:apple)&facet.field=category&facet.field=manufacture&fl=id&mm=2 Should return the documents containing "category with matching atleast 2 keywords [lcd,led or lcd,plasma or other valid combination] AND manufacture with matching atleast 2 keywords [sony,samsung or samsung,apple or other valid combination]"... -- View this message in context: http://lucene.472066.n3.nabble.com/mm-Minimum-Should-Match-tp4071197.html Sent from the Solr - User mailing list archive at Nabble.com.
