Yonik Seeley commented on LUCENE-2649:
--------------------------------------

bq.  It's just that perhaps we should "upgrade" the entry, if it was first 
created w/false and then the current call passes true?

We just need to watch the thread safety of stuff like this.
For Bits, it should be trivial... if you didn't ask for bits, you shouldn't be 
looking at it.
fasterButMoreRAM is different... upgrading an existing entry could be tricky.

> 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.
