Ryan McKinley commented on LUCENE-2649:
---------------------------------------
Ok, that makes sense -- what I mean is that you can not ask for the same *type*
with different parsers. Bytes, vs Strings, vs Ints all have different keys and
within the FieldCache, they are even stored in different Maps
What you can not do is as for a IntValues using: FieldCache.DEFAULT_INT_PARSER,
then switch to FieldCache.NUMERIC_UTILS_INT_PARSER for the same field.
make sense?
> 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.
