Subject [jira] Commented: (LUCENE-2907) termsenum bug when running with multithreaded search
Date Sun, 06 Feb 2011 10:23:30 GMT


Uwe Schindler commented on LUCENE-2907:

Yes the numbered states cache was always bugging me. But at least it is now synchronized (it
was not even that at the beginning). I think the problem may be that the parallel queries
doing different segments with different numbered states at the same time.

+1 to remove the cache and calculate on ctor, then its really stateless!

with a filter rewrite, and compares results)

rewrite and it will still fail.
