Shai Erera commented on LUCENE-2472:
------------------------------------

This is already set on IWC (set/getReaderTermsIndexDivisor).

So I guess all that's needed is to deprecate IW.getReader(int) on 3x and remove 
from trunk?

> The terms index divisor in IW should be set via IWC not via getReader

> The getReader call gives a false sense of security... since if deletions have 
> already been applied (and IW is pooling) the readers have already been loaded 
> with a divisor of 1.
> Better to set the divisor up front in IWC.
