Search Does Partial Word Match -- Don't Want This!

Was using the search (4.3) and noticed that it is doing a partial word match so if you searched for the word 'test' it is bringing up any product with words like 'tested' or 'cutest' Not good! How do you make it only do whole word searches?

There is no easy way to do it as the system should take into account the following words


Additional code modifications are required to do it.
