# 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,
  "aggs": {
    "top_hits_products": {
      "top_hits": {
        "size": 5
      }
    }
  }
}
```
