Michael McCandless commented on LUCENE-1613:
--------------------------------------------
John, do you have cases in practice where this is causing problems?
I understand the problem, and it's certainly real, and is not easy to fix
"automatically", but I'm wondering in practice whether the difference in the
resulting scores is ever significant.
I suppose we could make a "fixTermCounts()" method, which takes a looong time
as it iterates through the postings for each term to compute the actual count,
and then writes a new terms dict. The app would have to manually call this
method.
