Robert Muir commented on LUCENE-2265:
-------------------------------------
bq. I mean, high-level, users don't care about your automaton at all, much less
transitions. They want their regexes and wildcards to work.
but you have it backwards. users want their regexes and wildcards to work. they
want wildcard "?" or regex "." to match unicode
characters, not bytes. no one cares about bytes.
> 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.
