best way indexing user queries

[Martin Braun <mb...@uni-hd.de>]

Hello,

I would like to index the user submitted queries to a given index. As a
result of this I want to provide something like: people who searched for
test searched also with these queries: +title:test +author:somename.

I think the simple approach of just adding the queries as a string in a
document, would cause many redundancies, e.g. thousands of docs with
test in it.

Does anybody have programmed something similar, or is it just not a
reasonable idea?

thanks,
martin

Discussed before, it's more relation db task than lucene.

Simple approach is to get a list of terms from your queries and store 
relation document - query - terms.

I have around 1.6e10 query-terms in postgreSQL and with proper index 
select takes around 0.6 ms (clustered vacuumed analyzed), 300 ms after day.

You are looking for user based collaborative filtering. taste.sf.net can
do that for you.
