Adrien Grand updated LUCENE-4752:
---------------------------------
Attachment: LUCENE-4752.patch
I've tried playing with SegmentMerger to make it configurable. This could be
used to reorder document IDs (if you look at the diff in LuceneTestCase, all
that is needed to reorder doc IDs is to wrap the SlowCompositeReaderWrapper
with a SortingAtomicReader). Do you think it is a step in the right direction?

> It would be awesome if Lucene could write the documents out in a segment
> based on a configurable order. This of course applies to merging segments
> to. The benefit is increased locality on disk of documents that are likely to
> be accessed together. This often applies to documents near each other in
> time, but also spatially.
