for one thing it's not a good practice to generate an infinite indexable url-space made up of arbitrary search strings.

more specifically, url paths are case-sensitive and /search/Hello+World/ should return the same results as /search/hello+World/ or /search/Hello+world/ and i would suggest that at the bare minimum everything would be best folded to lower case as in /search/hello+world/


have you tried changing the search form to use the POST method to see if the problem disappears in that case?
