I have a type of matchmaking site and want users to be able to search more than one field from a drop down. For example, If someone wants to search both males AND females, how can I do that? The ‘select matching fields’ area is where I’m using it. I’d like to use a ‘both’ option in the search form that would return male or female, but it will only search for the actual string ‘both’, which obviously nobody is going to put under gender in their profile. I tried using a multi-select box, but that field type won’t show up in the ‘select matching fields’ area. Any ways to do this?

Thanks!
