Michael McCandless updated LUCENE-2265:
---------------------------------------
Attachment: LUCENE-2265.patch
New patch (from Robert & I) -- I think this one is ready to commit!
The rest of FuzzyQuery (eg LinearFuzzyTermsEnum) is now cutover to
code points (not UTF16 code units), and we've optimized various
methods in the automaton package (especially det). Performance of
automaton/fuzzy queries looks on par or a bit faster, compared to
trunk.
> improve automaton performance by running on byte[]

> Currently, when enumerating terms, automaton must convert entire terms from
> flex's native utf-8 byte[] to char[] first, then step each char thru the
> state machine.
> we can make this more efficient, by allowing the state machine to run on
> byte[], so it can return true/false faster.
