Update location search example docs
Update location search example docs

The examples in the docs for location_search show queries surrounded with braces, but those queries throw an APIError

APIError: Bad request. Please check the documentation: parameter 'location' must be one of the forms: 'geo:-21.22,40.0', 'clientip' or 'ip:127.0.0.1' 

This just updates the documentation.
