[FIX] website: fix matching of search term and fuzzy term

Prior to this commit, when a user searches with an upper case search
term of more than 3 characters, the search was considered as a fuzzy
search even if the result was an exact match.

Since the search is always lowered when there are more than 3
characters, the search is considered as fuzzy only when the search and
fuzzy term are case insensitively distinct.
