I should perhaps wait for the more seasoned hackers here - but one
thing that I've started to realize recently is that you frequently
need the same filters and validation for search parameters as you have
for forms that create/update things.  For example - if the create form
lowercases the email - then in the search you should lowercase it as
well.  Of course there will be some differences - but it should be
generally easier to start with the create profile and then derive a
search profile   from it then to start from scratch.

And for the parameter validation/filtering I would use some kind of
form parameter processor - as I've described at:
