Thanks for reviewing, Hoss! You are right, we could do that and I was actually
thinking about it already. The problem is if I make this fix than testFQ7 fails
for TestSimpleExplanationsOfNonMatches because it is assumed that all
non matching docs have a score of 0.0. I can easily change that, so that non
matching docs can either have a score of 0.0 or NaN but I was not sure if we
want that, because other scoring bugs resulting in a score of NaN (which we
will hopefully never have) wouldn't be noticed then anymore.
The reason why I argued that testFQ7 is an invalid test case is that it would
fail for any other query with a boost set to 0. Ironically we have this test
only for FilteredQuery, the only query class that ignores the boost, which
made it pass in the past.
