## Query history search

`GET /api/query-history`

Returns a list of queries in the query history that matches the search criteria. Query history search supports pagination. Use the `limit` parameter to control the maximum number of queries returned; the default limit is 100. You can also use the `page` query parameter to fetch queries from any page other than the first one.

Query parameters:

- **datasourceUid** - Filter the query history for the selected data source. To perform an "AND" filtering with multiple data sources, specify the data source parameter using the following format: `datasourceUid=uid1&datasourceUid=uid2`.
- **searchString** – Filter the query history based on the content.
- **sort** - Specify the sorting order. Sorting can be `time-asc` or `time-desc`. The default is `time-desc`.
- **onlyStarred** - Search for queries that are starred. Defaults to `false`.
- **page** - Search supports pagination. Specify which page number to return. Use the limit parameter to specify the number of queries per page.
- **limit** - Limits the number of returned query history items per page. The default is 100 queries per page.
- **from/to** - Specifies time range for the query history search. The time can be either epoch timestamps in milliseconds or relative using Grafana time units. For example, now-5m.

**Example request for query history search**:

```http
GET /api/query-history?datasourceUid="PE1C5CBDA0504A6A3"&datasourceUid="FG1C1CBDA0504A6EL"&searchString="ALERTS"&sort="time-asc" HTTP/1.1
