Huh. Well if you don't want the distance, don't put it in your "fl", wether it be in the request handler or the request. It may help to know that you can specify "fl" multiple times and the field list is ultimately the set of all of them. Given that, you could avoid putting distance:geodist(....) in your request handler definition; just pass it on the request when you want to compute it and of course have a lat & lon value. ~ David
