Hi,

A general question, I'm not trying to solve a problem.

What does ML do with unordered( <expr> ) ? I've run a couple of simple tests
- a straight pull of a 1000 nodes, 1200 nodes based on IDs in another
document (with warm caches)  and I see little or no difference.

My understanding is that the fragment IDs from the fact lists will already
be in database order. Any range indexes will require a sort to simplify the
intersection with any additional fragment ID lists, so there is little scope
for unordered to have an impact on performance.

Are there any scenarios where unordered is *likely* to provide a performance
benefit?

Thanks,
Lee
