OpenSearch: Added Index Browser to data source configuration and query
Selecting an OpenSearch index just got easier with the new Index Picker.
Finding and setting the right index in the Grafana OpenSearch plugin no longer means typing index names from memory. The query editor now includes a Select index button that opens a searchable browser of the indices available on your data source. Each index is shown alongside its document count and cluster health, so you can pick the right one at a glance. Search by substring, use * and ? for wildcards, or wrap your input in /…/ for a full regex match to quickly narrow down large clusters.
The Index Picker works with both Lucene and PPL query types. When you select an index for a PPL query, the editor automatically inserts or updates the source = <index> clause for you, and a pill next to the button shows your current selection with a one-click option to clear it. You’ll also find the Index Picker in the data source configuration, making it just as easy to set your default index when you first set up the connection.
