I've put up a preliminary version of the rewritten supersearch at http://london.openguides.org/kakemirror/supersearch.cgi
Profiling indicates this is way, way faster than the old version.
The summaries aren't working as I write, though they may be as you read. (I'm going to have some breakfast first though).
Please can everyone test this and give me feedback ASAP? Minor tweaking of the result ordering can be done later; I'm mostly interested in things that are glaringly wrong or obviously broken.
(It's not in CVS yet but it will be once I've eaten and checked it over. Search::InvertedIndex support is probably intact but also probably not as good with the ordering.)
Thanks,
Kake
