Fix for improving user search.

Currently Searches of users using search "firstname_<empty_spaces>_surname"
will only get valid matches if the _<empty_spaces>_ is a single empty spaces.

Change:
The search term string is squished to remove extra empty spaces. As a
result search terms like "Jill Bloggs" (one space between) and "Jill    Bloggs" (more than one space between) will both return the same results.
