Subject [jira] Commented: (LUCENE-2907) termsenum bug when running with multithreaded search
Date Sun, 06 Feb 2011 09:26:30 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2907?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12991130#comment-12991130

Uwe Schindler commented on LUCENE-2907:
---------------------------------------

Have you found out what happens or where a thread-safety issue could be? Each thread and each
query should have its own TermsEnum! Is there maybe a cache on codec-level involved? At least
there are no multiple-instance (static) caches in the  search-side of the TermsEnums, so there
must be a multi-threading issue in the underlying SegmentReaders.

To conclude: At least Robert found out that FieldCacheTermsEnum always works correct? Is this
true? The information on this issue is too small, there seems to be lots of IRC/GTalk communication
in parallel.

> This one popped in hudson (with a test that runs the same query against fieldcache, and
with a filter rewrite, and compares results)
> However, its actually worse and unrelated to the fieldcache: you can set both to filter
rewrite and it will still fail.
