The fq is evaluated independently of the q: For the fq a bitset is allocated, filled and stored in cache. Then the q is evaluated and the two bitsets are merged. Next time you use the same fq, it should be cached (if you have caching enabled) and be a lot faster. Also, if you ran your two tests right after each other, the second one benefits from disk caching. If you had executed them in reverse order, the q+fq might have been the fastest one. - Toke Eskildsen, State and University Library, Denmark
