You want to map each 'field' to a term prefix, and then give those
prefixes meaningful names for your users. So you'll end up with
something like "interests:(cars OR party OR friends) AND food:(pizza
OR spaghetti)" for the above.

If you're using omega, look at the documentation of the $setmap{}
OmegaScript command (talking about the 'prefix' map), and the
scriptindex documentation, which is the easiest way of generating
prefixes for omega.

If you aren't, look at the QueryParser documentation for an
explanation of how prefix mapping works.
