Hi there !,

We have 1M docs representing geolocalized polluting companies with the geographical diffusion of their pollution using isoline polygons

for instance  
[![](http://2.bp.blogspot.com/-aXeLo4ykrxc/T3juZYMm1SI/AAAAAAAAAA8/5RqL5dO4nXA/s400/isoline.png) ](http://2.bp.blogspot.com/-aXeLo4ykrxc/T3juZYMm1SI/AAAAAAAAAA8/5RqL5dO4nXA/s400/isoline.png)

to simplify we use rectangular area , check this drawing

> 10\_degree\_isoline 20\_degree\_isoline 30\_degree\_isoline geolocalised object DATA GENERATION (TOP 10 Company less polluting near a given point) A GIVEN POINT 1 Company 1 Company 2 We PREFER Company 1 (matching 10 degree isoline) than company 2 (matching...

We currently have the following mapping (you can change it if you think it's not relevant for the pb)  
doc ={

- 10units\_isoline = polygon # the area where the pollution generated by this company is about 10 units
- 20units\_isoline = polygon # the area where the pollution generated by this company is about 20 units
- 30units\_isoline = polygon# the area where the pollution generated by this company is about 30 units
- ..  
}

I dont manage to find the query to retrieve the top 10 companies that are the less polluting near a given point. In our context, we prefer documents where the queried point matches the polygon of the 10units\_isoline field more than a polygon of the 30units\_isoline field of another doc.

More specially (this is the difficult part) when we retrieve the TOP 10 document I want to know for each document what is the associated pollution isoline of this company at that particular point.

any direction / suggestion / similar examples where to search to get

(is ES the right tool for such query?)

Thanks in advance !

Nicolas
