 ## Narrow your search
 
 If you are looking for places in a particular region, or country, or only want to look in the immediate vicinity of a user with a known location, you can narrow your search to an area. There are different ways of including a region in your query. Mapzen Search currently supports three types: country, rectangle, and circle.
