If you want to query elastic search directly via uri you can use the source parameter. This parameter helps you to fire requests like this:

curl -XGET "http://localhost:9200/employee/_search?search_type=count&pretty" -d '{
  "aggregations": {
    "profile": {
      "terms": {
        "field": "_type"
      },
      "aggs": {
        "hits": {
          "top_hits": {
            "size": 1
          }
        }
      }
    }
  }
}'

directly via URL/GET:

curl -XGET 'http://localhost:9200/employee/_search?search_type=count&pretty&source={"aggregations":{"profile":{"terms":{"field":"_type"},"aggs":{"hits":{"top_hits":{"size":1}}}}}}'
