Subject [jira] Commented: (LUCENE-2111) Wrapup flexible indexing
Date Tue, 30 Mar 2010 16:19:27 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2111?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12851452#action_12851452

Michael Busch commented on LUCENE-2111:
---------------------------------------

bq. Flex is generally faster.

Awesome work!  What changes make those queries run faster with the default codec?  Mostly
terms dict changes and automaton for fuzzy/wildcard?

How's the indexing performance?


bq. I think net/net we are good to land flex!

+1!  Even if there are still small things to change/fix I think it makes sense to merge with
trunk now.

> Spinoff from LUCENE-1458.
> The flex branch is in fairly good shape -- all tests pass, initial search performance
testing looks good, it survived several visits from the Unicode policeman ;)
> But it still has a number of nocommits, could use some more scrutiny especially on the
"emulate old API on flex index" and vice/versa code paths, and still needs some more performance
testing.  I'll do these under this issue, and we should open separate issues for other self
contained fixes.
> The end is in sight!
