I often find it very difficult to locate the right document even with the "search". I'm often told that a document had a large number (ex: 25) of hits, but as none of the highlighted sequences are relevant I still have no idea which document contains what I'm looking for.
This is because the highlighting currently shows the _first_ hits rather than the _important_ hits. When I search for _two_ terms, I'd like to see highlight sequences that contain _both_ terms before sequences that contain only one term.
I've actually fixed this problem for my own Dokuwiki system (attached is a replacement inc/fulltext.php) ...but that doesn't help my use of Dokuwiki's hosted by others. The attached revision uses more complex regular expressions to first highlight sequences containing three (or two) words, and fall back silently and automatically to only one word when necessary.
