Description (last modified by olly) (diff)

Ability to run a postlist backwards - it's chunked, so this is feasible (with a small change we can even decode the current encoding backwards!) This is useful as we can add articles in date order and do a boolean search running the posting lists backwards to do "sort by date" (which is good as it an terminate once we've enough matches). Need this for gmane.

Now have patch to implement this for quartz, and change the matcher to make use of it. But either all backends need to support it, or the matcher needs to detect which is can do and use that (and a search over one quartz and one other needs to be handled...)
