look at http://issues.apache.org/jira/browse/LUCENE-1567 (New flexible query parser)

This new parser allows for internally rewrites/optimizes Query, and it is backward compatible.

Hi,
I am wondering if Lucene internally rewrites/optimizes Query. I am programatically generating Query based on various user options, and quite often I have BooleanQueri'es wrapped inside BooleanQueries etc.
Like,
((Src:Testing Dst:Test) (Src:Test2 Port:http)).
In this case, would Lucene optimize to remove the unwanted BooleanQueries ? Or more importantly, would these extra BooleanQueries cause any performance problems and should I fix my code to have a better Query ?

Thanks,
~preetham
