Search raw MySQL tables?

Hello,

I have a client who wants to sell @domain.com vanity email addresses. They have a MySQL db with a first names table, last names table, popular nouns table, and a table of unavailable email prefixes.

They want a user to be able to search for an email address. This would search the table of unavailable names first, then the other tables. If the name is available, it would return a price based on whether it’s a first name, last name or popluar noun.

Now: I figure I’m going to have to write something custom for this, but I’m hoping I can use plugins as well. Can I use Relevanssi to search a mysql table directly and return results?
