: doc1 is name=A B category=B : doc2 is name=A category=B : : when searching for the terms "A" and "B" I want doc2 to get a higher score. : to be more specific, I don't want the term "B" to influence doc1's score in : both <name> and <category>, only in one of them.
if you set the boost value of category to something very high, and set tie=0 you should get the exact behavior you describe. with tie=0, each clause (ie: "B") will only get a score contribution from the highest scoring field -- if the qf boost value for category is significantly higher then the boost value for "name" this should work fine. this is one of hte prime usecases for dismax: a "category" or "doc_type" field that has a very small finite set of values in it which frequently doesn't match anythin users type, but you configure it with a hight boost value so when it *does* match something the user types, it causes documents in that category (or having htat document_type) to dominate over other documents. -Hoss
