That's what the MemoryIndex in Lucene's contrib/ does. I tested it with a very fast incoming document stream (live blog posts from around the planet) and it held up well in my limited testing.

A profile is just a query (or I guess more than one query?) and you can setup a bunch of them. Then you supply the document and you will get the matching queries as well as a score. They say its the opposite of doing a search with a query and getting back docs. Instead you do a search with a doc and get back these queries. They claim it can be used for things like taxonomy/classification among other things. I don't know how true this is to a real reverse query system as that would seem to be kind of slow -- my guess is its a bit of an approximation. - Mark Endre Stølsvik wrote: > > May I ask: What IS a profilenet?
