# 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:
|
||
|
|
|
||
|
|
```json
|
||
|
|
GET opensearch_dashboards_sample_data_ecommerce/_search
|
||
|
|
{
|
||
|
|
"size": 0,
