multiple select box or checkboxes in the registration form

If you have a limited amount of searchable fields, would a dropdown box of the options work? So the dropdown would have the over_18, love_us or whatever in there and a go button that fires off the query? AJAX would be ideal for this, but I'm terrible at that, so it would be pretty easy to just refresh the page on go and fire off that query.

One thing you could do is some sort of table sorter that lets you filter people that way. I'm not sure if you're starting with an entire table with all the users and they are filtering from there or if you are starting with something blank and only allowing them to see results they ask for. If there is a whole table, you could create the table with something to convert the 1 or 0 back to yes or no and then you could use this plugin

That allows people to multisort the columns (They can even control click to get all the people who are over 18 and THEN people who love userspice. Just a thought.
