title: ElasticSearch find document exact match using lat/long
body: <p>I have this field mapping in my index:</p>
  
  <pre><code> "businessLocation": {
              "type": "geo_point"
            },
  </code></pre>
  
  <p>I wanted to find documents using exact match with my <code>lat/long</code> coordinates. I've tried <code>geo_distance</code> however, there's a requirement that my distance be greater than 0. </p>
  
  <p>I even tried this query:</p>
  
  <pre><code>{
    "query": {
      "bool": {
        "must": [
          {
            "query_string": {
              "default_field": "businessLocation",
              "query": "src.lat = 34.47  AND src.lon = -122.37"
            }
          }
        ]
      }
    }
  }
  </code></pre>
  
  <p>However, I got this error:</p>
  
  <pre><code>Geo fields do not support exact searching, use dedicated geo queries instead: [businessLocation]
  </code></pre>
