elasticsearch_geo_distance_example

# Manually create the index
curl -XPUT 'http://localhost:9200/pins/'

# Create proper mapping
curl -XPUT 'http://localhost:9200/pins/pin/_mapping' -d '
{
    "pin" : {
        "properties" : {
            "location" : {
                "type" : "geo_point"
            }
        }
    }
}'

# Inserting a pin
curl -X POST "http://localhost:9200/pins/pin/1" -d '{
    "pin" : {
        "location" : {
            "lat" : 40.12,
            "lon" : -71.34
        },
        "tag" : ["food", "family"],
        "text" : "my favorite family restaurant"
    }
}'

# Since we're running these curl calls back to back, lets refresh
curl -XPOST 'http://localhost:9200/pins/_refresh'

# Now let's search by geo_distance
curl -X GET "http://localhost:9200/pins/_search?pretty=true" -d '{
    "query" : {
        "filtered" : {
            "query" : {
                "match_all" : {}
            },
            "filter" : {
                "geo_distance" : {
                    "distance" : "120km",
                    "pin.location" : {
                        "lat" : 40,
                        "lon" : -70
                    }
                }
