Querying for exact match SSID name

[Bryce]

I have a set of reference ESSIDs that I'm trying to query through WiGLE. One thing I've noticed using the query interface is that the results seem to do approximate matching, so if I search for say "john", i'll get results not only for "john", but also "JOHN" and "johns iPhone". Is there anything I can enter into the search box (or send along with the request programatically for that matter) that will limit the results to an exact match?

Many thanks, Bryce.
