# $stats

`$stats` returns multiple basic metrics in one pass.

For the selected field, it computes:

- `count`
- `sum`
- `min`
- `max`
- `avg`

This is equivalent to running `$count`, `$sum`, `$min`, `$max`, and `$avg` together, but returned as a single object.

### Compatibility

| Field Type | Supported |
|------------|-----------|
| TEXT | No |
| U64/I64/F64 | Yes |
| DATE | Yes |
| BOOL | Yes |
| KEYWORD | No |
| FACET | No |

Field must be `FAST`.

### Arguments

| Argument | Type | Required | Description |
|----------|------|----------|-------------|
| `field` | `string` | Yes | Field to aggregate. |
| `missing` | `number` | No | Fallback value for missing fields. |

SEARCH.AGGREGATE products '{}' '{"price_stats": {"$stats": {"field": "price", "missing": 0}}}'
```

### Output

```json
{ "price_stats": { "count": 9, "min": 0, "max": 80, "sum": 360, "avg": 40 } }
```

`min`, `max`, and `avg` can be `null` when no values are available.
