Search Sort: `_geo_distance` sorting

[kimchy]

Allow to sort by _geo_distance. Here is an example:

{
    "sort" : [
        {
            "_geo_distance" : {
                "pin.location" : [-40, 70],
                "order" : "asc",
                "unit" : "km"
            }
        }
    ],
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

What is the role of "unit" here? That is, the distance sort should always return hits in the same order regardless of unit of length, shouldn't it? Thanks.

[kimchy]

Yes, it will. This ties into the ability to get the sort value(s) for each hit, and allows you to get it either in km or miles.

to use sorting, Will I have to always use pin.location only as centre location ?
