1) Change line 514 to "$errors[] = array('searchnoresults', '');"
2) Add "$cl->SetFieldWeights(array('title' => 100, 'pagetext' => 10));" after line 410 and change those values to your liking (see here http://sphinxsearch.com/doc.html#weighting)
3) Search cache? It's definitely not using vB built-in search caching because that one is horribly ++++ed up

Tag search is not yet enabled but luckily for us Sphinx supports multi-valued attributes (http://sphinxsearch.com/doc.html#mva) so we can store all tags for every thread. As soon as I get my hands on a 3.7 installation I can implement that.

Prefix search... I can't believe how ++++ing retarded vB is. Prefixes don't get an id, they are just stored as strings (there is no unique integer id in the table). Sphinx doesn't support string attributes. I'm a bit at a loss here. Possibly a very simple hashing function... but it'd have to be implemented in MySQL... what were they thinking
