Aytek Ekici commented on SOLR-236: ---------------------------------- Hi Martijn, Intersection of results sets is also a kind of "AND", right? Intersection result of A docset and B docset is equal to resultset of "conA AND condB" i think. Your suggestion "fq=lat:[37.2 TO 39.8] AND lng:[24.5 TO 29.9]" works. And also Anil's suggestion "fq=+lat:[37.2 TO 39.8] +lng:[24.5 TO 29.9]" works. But they don't allow multiple selections for a facet field. I can't use excludes. It throws parsing errors. Using "AND" between two filters in a filter query results with one item in FilterList of QueryCommand, that must be the reason not to be able to parse/support ex/tag things there i guess. I have two solr instances here one with patch and another without patch. And i just copied configurations and data from one to other. Only difference is field_collapsing patch as i can see. I'm trying to see what makes the difference in results but new in solr so it takes time to see/catch what is going on. So any help/tip would be appreciated.
