Yonik Seeley commented on LUCENE-2649:
--------------------------------------
bq. I guess we need to be able to manually configure FieldCache with some kind
of FieldType.
I don't know how well that would work. For one, there's only one FieldCache,
so configuring it with anything seems problematic.
Also, if I have to list out all the fields I'm going to use, that's another big
step backwards.
A factory would be a pretty straightforward way to increase the power, by
allowing users to populate the entry through any mechanism, and optionally do
extra calculations when the entry is populated (think statistics,
sum-of-squares, etc).
> FieldCache should include a BitSet for matching docs

> The FieldCache returns an array representing the values for each doc.
> However there is no way to know if the doc actually has a value.
> This should be changed to return an object representing the values *and* a
> BitSet for all valid docs.
