Subject [jira] Commented: (LUCENE-2649) FieldCache should include a BitSet for matching docs
Date Fri, 24 Sep 2010 17:29:33 GMT


Ryan McKinley commented on LUCENE-2649:

bq. Can't we first just allow the retrieval of ByteValues, etc, that also have Bits on it?

I sure *hope* so... otherwise, I doubt anything will move forward.  

My hope with LUCENE-2665, is to fix the basic problem -- in a way that does not close the
door to the improvements we want to make in the future.  I think/hope we are close.  

If I'm missing something let me know, so I can stop wasting my time.

(I don't even know what CSF is, and do not want to learn right now)

> 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.
