Time limit between searches?

Perhaps check this condition

PHP Code:

$_SESSION['last_search'] + $limit < time()

Hmm, this really has me stumped.
As far as i'm aware the first time the user searches, the if statement should return false since $_SESSION['ip'] isn't set yet, so it should skip to the else statement and record the current time of the search. The 2nd time they try to search, the $_SESSION['ip'] var should be set, and then it should check if the recorded time of the first search + 10 seconds is greater than the current time. Obviously that can't be correct or it would work but... how is it wrong? haha
