# List Query Latency Collections

`GET /v2/queries/latency/collections`

The collections that ran queries in the window, most active first.

For organizations with more collections than the metrics response returns
series for, so a picker can search the rest without asking for every
series at once.

## Query parameters

- `from` string, nullable
- `to` string, nullable
- `search` string, nullable
- `limit` integer
- `offset` integer
- `collection` string, nullable
- `api_version` string, nullable
- `rerank` string, nullable
- `search_mode` string, nullable
- `has_filter` string, nullable

## Response `200`

Successful Response

- QueryLatencyFacetsResponseV2 — Searchable collection list for the latency picker, so a large organization never needs every series in one response.
  - `collections` LatencyCollectionFacetV2[]
    - `collection_name` string, required
    - `query_count` integer, required
  - `has_more` boolean, required
  - `limit` integer, required
