We are using ElasticSearch 5.0.0.

Please find data in movies index in ElasticSearch in attachment.

Please let us know if there is a simpler query or any other way to perform the aggregation query given in snippet below on all the fields of index in mapping instead of just this single column.

    }
  },
  "aggs": {
    "distinct_tables_1": {
