Earwin Burrfoot commented on LUCENE-2265:
-----------------------------------------
So? You aren't making some generic automaton library, are you?
Get these user regexes/wildcards/etc, convert them to utf-8, build utf-8
automaton, run it against lucene data.
> improve automaton performance by running on byte[]

> Key: LUCENE-2265
> URL: https://issues.apache.org/jira/browse/LUCENE-2265
> Project: Lucene - Java
> Issue Type: Improvement
> Components: Search
> Affects Versions: Flex Branch
> Reporter: Robert Muir
> Priority: Minor
> Fix For: Flex Branch
>
> Attachments: LUCENE-2265.patch
>
>
> 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.
