----------------------------------------------------------------
One of the nocommits in the patch is about the use of an Filter for the parent
filter.
NesteDocumentQuery uses an OpenBitSet from this Filter for next() and advance()
just like a Filter and also as a parent filter.
So how about adding sth like this:
{code}
public abstract class ParentFilter {
public abstract ParentDISI getParentDISI(IndexReader reader);
}
public class ParentDISI extends DocIdSetIterator {
public int getParent(); // to be used only after next() or advance() returned
<> NO_MORE_DOCS
}
{code}
together with another constructor for NestedDocumentQuery with a ParentFilter
argument?
