Global aggregations

The global aggregations lets you break out of the aggregation context of a filter aggregation. Even if you have included a filter query that narrows down a set of documents, the global aggregation aggregates on all documents as if the filter query wasn’t there. It ignores the filter aggregation and implicitly assumes the match_all query.

The following example returns the avg value of the taxful_total_price field from all documents in the index:

GET opensearch_dashboards_sample_data_ecommerce/_search
{
  "size": 0,
  "query": {
    "range": {
      "taxful_total_price": {
        "lte": 50
      }
    }
  },
  "aggs": {
    "total_avg_amount": {
      "global": {},
      "aggs": {
        "avg_price": {
          "avg": {
            "field": "taxful_total_price"
          }
        }
      }
    }
  }
}

Example response

...
"aggregations" : {
  "total_avg_amount" : {
    "doc_count" : 4675,
    "avg_price" : {
      "value" : 75.05542864304813
    }
  }
 }
}

You can see that the average value for the taxful_total_price field is 75.05 and not the 38.36 as seen in the filter example when the query matched.
