I understand that lucene's AND (&&), OR (||) and NOT (!) operators are shorthands for REQUIRED, OPTIONAL and EXCLUDE respectively, which is why one can't treat them as boolean operators (adhering to boolean algebra).
I have been trying to construct a simple OR expression, as follows q = +(field1:value1 OR field2:value2) with a match on either field1 or field2. But since the OR is merely an optional, documents where both field1:value1 and field2:value2 are matched, the query returns a score resulting in a match on both the clauses. How do I enforce short-circuiting in this context? In other words, how to implement short-circuiting as in boolean algebra where an expression A || B || C returns true if A is true without even looking into whether B or C could be true. -Deepak
