# 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:
|
|
|
|
```json
|
|
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
|
|
|
|
```json
|
|
...
|
|
"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. |
