Sure. But with incremental searching, the result size is always one, right? ;-)
No. You

The win here is actually partitioning the object cache...
Similar wins could be achieved without making backup/pack/etc more

2. Use an N-best algorithm. If N is the size of the batch and M is
the corpus size, then this is O(M*ln(N)) rather than O(M*ln(M)) which
is a significant improvement if N M, but still quite expensive.
