this is the purpose the relevance rating in SearchMatch, of course ... what we 
don't do right now is allow for a second pass at the match to rank it: we 
expect it to be ranked by the time it appears in the UI.

that could be a very larg db ;) it would also need to be opt in out of privacy 
concerns.

i think this is certainly something worth doing.


another possibility is to have post-match runners go over the matches thus far 
returned and rank them. for instance, if Amarok returns "Play music by the 
White Stripes" and strigi returns "white_stripes.png" then a nepomuk based 
runner might be able to return the information that they had recently 
received white_stripes.png and so may well be interested in that more due to 
recency, or maybe they had tagged that file with 5 stars or somesuch.

to do this would require a post-match relevancy ranking system.
