Subject [jira] Commented: (LUCENE-2265) improve automaton performance by running on byte[]
Date Fri, 02 Apr 2010 23:41:27 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2265?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12853005#action_12853005

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.

> 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.
