# cat count

The cat count operation lists the number of documents in your cluster.

## Example

```json
GET _cat/count?v
```

To see the number of documents in a specific index or alias, add the index or alias name after your query:

```json
GET _cat/count/<index_or_alias>?v
```

If you want to get information for more than one index or alias, separate the index or alias names with commas:

```json
GET _cat/aliases/index_or_alias_1,index_or_alias_2,index_or_alias_3
```

## Path and HTTP methods
