Get geoObjects from cache, which contains (not contained in) some polygon #461

Hi, I need to check which polygons in my cache contain some other polygon. I saw that 'within' command return only objects that are fully contained inside of a specified bounding area. It's the opposite case.

Maybe i can use the 'Intersects' command and check the overlap percentage, but I don't know if such ability exists in tile38.

You can first, as you suggested, find ids of all things that intersect with your polygon of interest p, and then call

TEST GET collection p_id WITHIN GET collection id

for each id returned by INTERSECTS. If p is not in the same collection, you can specify it directly. See https://tile38.com/commands/test/ for details.
