Where and how do you store this type of info: If user U1 search for query Q7 boost doc D5 by B17 If user U2 search for query Q3 boost doc D15 by B2 Seems lots of info, and it must be persistent.
Perhaps o.a.l.search.function can help - assuming you have this info available at search time, and can use it to create a ValueSource.
