Hi, We're looking at implementing commutability / reachability search to our users with isochrones e.g. https://en.wikipedia.org/wiki/Isochrone_map.
There are a number of open and commercial services which we are looking at. Some of these, in particular with public transport, return multiple polygons (e.g. train then walk). Does Solr allow multi-polygon spatial search (with and without holes)? and how performant might that be? We would do a bounding box filter first. Many thanks in advance, Dan
