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
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.
