I've looked for an answer, but there's nothing worse than doing a search that includes the keyword "search"

I was wondering if there was any reporting available for Onsite Search... you know, searches that are done for products on your web site. I would like to see what people are searching for.

My client is running Zen Cart v. 1.3.9d, probably waaay out of date, but my hands are tied.

Thanks!
