As nmweb said if you want to identify all keywords in the search input you are going to do a lot of checks. For instance the search 'users who's name contains me'. The str_word_count will get the who with the added 's string. And the who here is only valid with the user and name parts of the search string.

There is no easy solution for this otherwise it would be floating around already
