Michael McCandless commented on LUCENE-3260:
--------------------------------------------

Thanks Shai!

The 200+ iterations are exceptionally fast since they only do 1 TermsEnum op 
per iter (it's the indexing that'll be slow in this test -- for that I do 
numDocs = atLeast(10)).  Also, this bug only happens when seekExact is followed 
by next, only on certain terms, and only on a multi-seg index.  So it seems an 
OK investment of CPU for test coverage ;)

> need a test that uses termsenum.seekExact() (which returns true), then calls 
> next()
