Hi,

I've just had Lucene installed on my server, and I can't find out how to sort the result by the given score (percentage). Anyone now how to do this?

Thanks,
Børge Warvik

I've written a (currently unpublished) extension for this purpose. It's a template operator that takes a Lucene result set and returns it sorted by score. It's not documented or anything, but if you like, I can publish it on /community/contrib.

Done. The extension is available at http://ez.no/community/contribs/template_plugins/lucene_score_sorting

Hi Børge

What's the problem here? Results are sorted by score by default.
Or is it with multiple sorting criteria?

It's not if you use <i>subtree_array</i> to include only certain parts of the site in the search.

OK, a very quick review of the code did not yield the culprit, no time to look closer now, but this is a bug.

I'll check later when I've more time.

Hi Paul,

It's my mistake. I didn't know that no sorting attribute in the fetch statement would give this sorting... my bad :) Couldn't find anything about that reading the comments... but I've probably just missed it.
