# $count

`$count` returns how many documents contribute a value for a field.

### How It Works

* By default, only documents that have the field are counted.
* If `missing` is set, documents without the field also contribute to result.

### Compatibility

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

Field must be `FAST`.

### Arguments

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