I want to write a geospatial view that takes searches for the following document within a one mile radius from a given latitude and longitude. How do I do this?

```
{
   "agree_allowed":true,
   "assigned_by":"",
   "assigned_to":"",
   "comments_allowed":true,
   "location": {
    "coordinates": [
      "-74.168868",
      "40.854655"
    ],
    "type": "Point"
  },
   "subscribed":{
      "user_cfd29b81f0263a380507":true,
      "user_cfd29b81f0263a3805010":true
   },
   "type":"report",
   "user_id":"user_cfd29b81f0263a380507",
   "username":"test17"
}

```
