Subject Re: Increasing filterCache size and Java Heap size

Yes. Each entry is roughly 1K + maxdoc/8 bytes. The maxdoc/8 is the
bitmap that holds the result set and the 1K is just overhead for the
text of the query itself and cache overhead. Usually it's safe to
ignore since the maxdoc/8 usually dominates by a wide margin.
