Better b2-search and better display of search results:

- option: show only the post title as proposed earlier here: http://forums.b2evolution.net/viewtopic.php?t=7872&highlight=search
http://forums.b2evolution.net/viewtopic.php?t=7508&highlight=search

- Display search results like google with text excerpts around the search terms

- option: sort by relevance

Might be difficult, I don't know, but after I've found plugins for Wordpress with this features, I thought, maybe a b2-hack could be possible as well?
