```













Returns counts for each item present in the sketch. 
Multiple items can be requested at once.
Please note this number will never be higher than the real count and will likely be lower.

This command has been deprecated. The count value is not a representative of
the number of appearances of an item.

## Parameters

* **key**: the name of the sketch where items are to be counted.
* **item**: the items to be counted.

## Examples

```
redis> TOPK.COUNT topk foo 42 nonexist
1) (integer) 3
2) (integer) 1
3) (integer) 0
```
