Yup, Lance is right. But it won't always work if you have multi-valued data since it wouldn't match a document that had a point both in the ring and the hole.
Another approach that internally works faster and addresses the multi-value case is to implement a custom Spatial4j Shape. In this case, you could create a special aggregate Shape that basically accepts one shape and excludes the other, in its custom relate() method. It's like a subtracting shape. This is generically useful and on my list of things to do but I haven't had the need. The other step would be parsing it somehow, so you might do that by extending the existing spatial 4 field type. ~ David Lance Norskog-2 wrote > Outer distance AND NOT inner distance? > > On 04/12/2013 09:02 AM, kfdroid wrote: >> We currently do a radius search from a given Lat/Long point and it works >> great.
