Sometimes your work might require that all the search results be from a particular country. To do this, you can set the `boundary.country` parameter value to the alpha-2 or alpha-3 [ISO-3166 country code](https://en.wikipedia.org/wiki/ISO_3166-1).

If you're going to attempt using multiple boundary types in a single search request, be aware that the results will come from the intersection of all the boundaries. So if you provide regions that don't overlap, you'll be looking at an empty set of results. You've been warned. Here's an image of how it works:
Many use cases call for the ability to promote nearby results to the top of the list, while still allowing important matches from farther away to be visible. Mapzen Search allows you to prioritize results within geographic boundaries, including around a point, within a country, or within a region.
### Prioritize around a point
By specifying a `focus.point`, nearby places will be scored higher depending on how close they are to the `focus.point` so that places with higher scores will appear higher in the results list. The effect of this scoring boost diminishes to zero after 100 kilometers away from the `focus.point`. After all the nearby results have been found, additional results will come from the rest of the world, without any further location-based prioritization.
