Use a regular expression, something like \s+USE\s would do it. Make sure to tick the box saying "Regular Expression" in the find dialog (or hit cmd-alt-r to toggle it.)

Thanks!

Now, this regular expression also finds:

anything here USE test

while I only want the search to be true if there is noting in front of USE, ONLY spaces.
