search fields

I would like to create a search form similar to the one found on http://www.oodle.com/ . It has 2 search fields. The first is the "what" which searches the database fields of "title", "description", and "category" and the second field searches the "where" of the database fields "city", "state" and "zip". Is it possible to program Php runner to do this and if so how with as much detail as possible. I already have each of these fields in the database but I do not like the basic search where you can only search on one field at a time. The advanced search is too much. I want the search like on oodle on top of a whole section of pages on a site.
Thanks in advance.
