For speed you might want to consider an extra field in the DB in the
future. If the database gets larger, or your query needs to join several
tables together, then things will take a noticeable speed hit. I had a
similar issue myself where I had to search for names based on
mis-spellings of them. In the end I searched with metaphone tags on an
extra field in the DB set up for that purpose, but it was the only way
to do it that didn't affect the speed of the site.
