Attachment: LUCENE-1061.patch
bq. The hoops we jump through because we're in Java.... sheesh. :)
Alas, yes... maybe we should all switch to Erlang! ;)
bq. What might be even more interesting is to make the newXXX methods return
Query instead of a specific type. I'm not sure if that would work in all cases
(surely not for BooleanQuery), but might for most of 'em.
OK I was able to do this with many of them -- attached new patch. Only
PhraseQuery, MultiPhraseQuery, BooleanQuery/Clause required strong typing. All
others now return Query.
