In ES you need to aggregate according to App_categor, and the JSON query statements are as follows:

{"  query": {"bool": {"      must": [{"Term          ": {            "Flag_color": "3"          }        },        {          " term ": {            " atype ":" 0 "          }        },        {          " term ": {            " Flag_off ":" 0 "          }        }      ]    }  },  "Explain": true,  "Aggs": {"    appcategory": {      "terms": {//The aggregation field is the letter        "field": "App  _category ",  //aggregate field        " Order ": [//Sort by the letter of the aggregated field          {            " _term ":" ASC "          }        ],        " size ":                 //Aggregation Displays the number of results (default 10)}}}}
