Ryan McKinley updated LUCENE-2649:
----------------------------------
Attachment: LUCENE-2649-FieldCacheWithBitSet.patch
I added a static flag to CachedArray:
{code:java}
public abstract static class CachedArray {
public static boolean CACHE_VALID_ARRAY_BITS = false;
public final Bits valid;
public CachedArray( Bits valid ) {
this.valid = valid;
}
};
{code}
and then set it to true in the SolrCore static initalizer.
If folks are ok with this approach, I'll clean up the javadocs 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.
