John Wang commented on LUCENE-1613:
-----------------------------------
Maybe to just add a javadoc comment on the call to explain the behavior in this
case?
Many times calling docFreq happens in a readonly context, calling
expungeDeletes in that context is not a good idea.
I agree it is not trivial to fix while keeping the performance. I don't mind
closing the bug either.
