 > Time complexity: O(V+N+log(M)+N*V) where V is the number of vertices in the polygon, N is the number of elements inside the bounding box of the circular area delimited by center and radius of the polygon's bounding circle and M is the number of items inside the index.
 
-Search for members inside a simple polygon described by 3 or more coordinates. This command determines the polygon's center and farthest vertex from it to perform a `GEORADIUS`. The results are then filtered using a Point-In-Polygon (PIP) algorithm ([source](http://alienryderflex.com/polygon/)) that provides indeterminate results for members on the edges.
