Top hits aggregations

The top_hits metric is a multi-value metric aggregation that ranks the matching documents based on a relevance score for the field that’s being aggregated.

You can specify the following options:

  • from: The starting position of the hit.
  • size: The maximum size of hits to return. The default value is 3.
  • sort: How the matching hits are sorted. By default, the hits are sorted by the relevance score of the aggregation query.

The following example returns the top 5 products in your eCommerce data:

  1. GET opensearch_dashboards_sample_data_ecommerce/_search
  2. {
  3. "size": 0,
  4. "aggs": {
  5. "top_hits_products": {
  6. "top_hits": {
  7. "size": 5
  8. }
  9. }
  10. }
  11. }
