Hi, I am trying to store road geometry as linestring (geo\_shape). I would index millions of road geometries in the geometry field of my documents. Each road will have its separate document. While going through reference of 5.6, i found few parameters for geo\_shape type. I did also go through some discussions here. But was left confused between below parameters, need some help here to achieve faster indexing and querying. 1. tree = geohash or quadtree ? (they say quadtree is faster) 2. precision = what is default ? should i really set it for small shapes like roads ? 3. distance\_error\_pct = I am thinking of staying away from this stuff. Any comments ? ---
