Keep track of search requests on your forum?

[Trillian]

How can I keep track of what key words people use to search on my forum? And I am also finding a need to track if people search for posts on other members. When I go to the database, I only see the last few search queries in there, but I'd like to see all of them from the past 30 days (excluding the "New Posts" type of searches).

I searched for a hack on here but couldn't find one, but I possibly didn't search hard enough. Any suggestions?

That will be a great feature, I also have a similar request. But no answer until now.
