> List the names of all rerank cache namespaces.

URL: https://docs.hotkv.com/commands/rerank-list/

```
RERANK.LIST
```

- Group: Keyed caches
- Complexity: O(N) where N is the number of namespaces
- HotKV Cloud: Performance and Scale plans
- On-Premise: requires the rerank-cache license feature

The rerank cache stores cross-encoder rerank scores for a query and document pair in a retrieval pipeline, so a repeated pair does not have to be scored again. `RERANK.LIST` returns the names of all namespaces on the server
you are connected to, in no particular order. In a cluster, each node lists
only the namespaces it holds.

## Return value

| Case | RESP2 | RESP3 |
| --- | --- | --- |
| Always | Array of bulk strings (empty if there are none) | Same |

Errors:

- `ERR wrong number of arguments for 'rerank.list' command` if the argument count is wrong.
- `NOLICENSE rerank-cache requires a HotKV license. Contact sales@hotkv.com` if your license does not include the `rerank-cache` feature.

## Examples

```
