Alex,

It would be a good idea to add the IP routines to the search_log entries. That way, the same IP searching 10x for flowers in say 60 minutes, wouldn't be counted more than once.

This would prevent some people who can enter the same term 20 times in 5 minutes hoping a different answer will come out from skewing the results... since it's not the number of searches per se, but the number of 'visitors' looking for a thing that's important.
