I have several questions regarding geographical queries,
is it possible when doing a shape or polygon query to use the shape or polygon queries of another document, and not have to pass this information through the network, so basically you could refer to a field in another document in your query.
is it possible to make a search on multiple fields in a document that represent coordinates, for example
3.is it possible to ask for all the points that fall within a shape or polygon or distance from a point but also specify not to return any point that do or do not fall within another polygon, so basically a Inner join or Left or right join.
4.is it possible to combine shape or polygon queries with GeoHashing, for example do a query that says give me all the document that fall within this GeoHash but do or do not fall in this polygon, again a inner join or left or right join scenario.
finally what are the performance implications?
