Uwe Schindler updated LUCENE-3823:
----------------------------------
Attachment: LUCENE-3823.patch
Patch. Tests mostly pass, there is still some insane FieldCache in some tests
(thats unrelated to this change, but can be made appearing more often by
remving rarely() from the maybeWrapReader method. Mostly affected is insane
field cache in TestExplanations and QueryUtils that check explanations.
The attached patch simply implement the vertical index splitter in
test-framework. If there is interest in this FilterAtomicReader, we can move it
e.g. to core.
> Add a field-filtering FilterAtomicReader to 4.0 so ParallelReaders can be
> better tested (in LTC.maybeWrapReader)

> In addition to the filters in contrib/misc for horizontally filtering (by
> doc-id) AtomicReader, it would be good to have the same vertically (by
> field). For now I will add this implementation to test-framework, as it
> cannot stay in contrib/misc, because LTC will need it for maybeWrapReader.
> LTC will use this FilterAtomicReader to construct a ParallelAtomicReader out
> of two (or maybe more) FieldFilterAtomicReaders.
