Subject [jira] Commented: (LUCENE-2265) improve automaton performance by running on byte[]
Date Fri, 02 Apr 2010 23:47:27 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2265?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12853008#action_12853008

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.

> 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.
