Normally, space is just a character as good as any other. Looking for
a couple of spaces should return all records containing a couple of
spaces.
If you are writing your own search routine, you can scan through
the search string beforehand - this should be a no-brainer :-)
The only problem I can think of is when responding to Find Manager
requests. You don't have control how the search string is being
"prepared" before Find inquires your application. But you can change
your response routine to use the original search string (which however
might slow down things significantly).
