Hello,

I have a set of about 250,000 polygons. Each of them contains a field  
called geo, containing a geo\_shape value (polygons). Querying against it  
using a construct like this:

{  
"fields": [],  
"query": {  
"match\_all": {}  
},  
"filter": {  
"geo\_shape": {  
"geo": {  
"shape": {  
"type": "Polygon",  
"coordinates": [  
... Points ...  
]  
}  
}  
}  
}  
}

causes a query time of multiple seconds. I tried using both quad trees and  
geohashes. I am querying for estates using polygons of streets, districts,  
etc. Is there a way to speed up my query?

Assuming you are using 0.90, try to reduce the precision or tree\_levels in  
the mapping for the field to a few hundred meters.

If you aren't using 0.90, you should upgrade because that release contains  
several geo\_shape related fixes.

I have a similar data set (flickr neighborhood polygons) of about over 200K  
shapes of varying sizes. Especially things like continents and other large  
polygons are very hard on the index. I basically use several types with  
different precision/tree\_levels. For things like countries, I don't need a  
lot of accuracy.
