Uwe Schindler commented on LUCENE-1345:
---------------------------------------
The idea behind the patch was to merge the code of filters and queries. Further
optimizations now can remove the score calculation from the filter code.
Using my patch you are now be able to add filters to BooleanQueries or directly
execute them using Searcher.search, because they are subclasses of Query.
Further optimizations now may remove the score computation in complete, if the
given query extends Filter (if (query instanceof Filter) do something other).
