: i was wondering how the following query might be processed: : : ?q=*:*&fq=+tags:(Gucci)&fq=-tags:(watch sunglasses)
they are intersected so only documents matching all of them are potential matches. : and if there is a difference to a query with only one fq parameter like : : ?q=*:*&fq=+tags:(Gucci) -tags:(watch sunglasses) : : I am aware of the chaching implications but i am not sure how the set : intersections work between the results of the 'q' and one or more 'fq' : parameters and if it is possible to use boolean operators inside a : filter query. filter queries an use an QParser, so you can use boolean operators if the QParser supports it (by default the QParser is "lucene" so "yes") ... i don't understand the "i am not sure how the set intersections work between the results of the 'q' and one or more 'fq'" part of your question, can you clarify what it is you are asking? -Hoss
