Martijn van Groningen updated LUCENE-3602:
------------------------------------------
Attachment: LUCENE-3602.patch
Attached a new patch!
* The static method now has Query as return type.
* TermsCollector and TermsQuery are package protected.
* TermsQuery now holds an int[] ords instead of an array of ByteRefs. This is a
really nice improvement :)
* Swapped the const args of TermQuery. Consistency is important!
* After [some
discussion|http://colabti.org/irclogger/irclogger_log/lucene-dev?date=2012-01-16#l231]
moved the classes back to o.a.l.search.join package.
* The query time joining uses the dict comparator on all places now (instead of
ByteRef#UTF8AsUnicode).
In the that cmp==0 in TermsQuery at line 121; YES_AND_SEEK can't be returned.
The FilteredTermsEnum prohibits seeking to a term smaller or equal then the
current term.
