Trash authorizes each hit against a single index's group and resource. A federated search joins in hits from another index, which would then be checked against the wrong one, so trash and federation cannot be combined. Refused in two places. searchServer.Search rejects the request before it resolves the federated indexes, because resolving one can build an index. The bleve index repeats the check for callers that reach it directly, next to the rule that keeps trash-only fields out of a live search, so a read path cannot apply one rule without the other. The only caller that sets both flags is the legacy /api/search?deleted=true path, which federates dashboards and folders whenever no type is given. That path returns nothing today: deleted objects only enter the index when index_deleted_documents is set, and it defaults to off. Nothing in the frontend calls it either, so this turns an empty response into an error rather than changing a working one. |

The open-source platform for monitoring and observability
Grafana allows you to query, visualize, alert on and understand your metrics no matter where they are stored. Create, explore, and share dashboards with your team and foster a data-driven culture:
- Visualizations: Fast and flexible client side graphs with a multitude of options. Panel plugins offer many different ways to visualize metrics and logs.
- Dynamic Dashboards: Create dynamic & reusable dashboards with template variables that appear as dropdowns at the top of the dashboard.
- Explore Metrics: Explore your data through ad-hoc queries and dynamic drilldown. Split view and compare different time ranges, queries and data sources side by side.
- Explore Logs: Experience the magic of switching from metrics to logs with preserved label filters. Quickly search through all your logs or streaming them live.
- Alerting: Visually define alert rules for your most important metrics. Grafana will continuously evaluate and send notifications to systems like Slack, PagerDuty, VictorOps, OpsGenie.
- Mixed Data Sources: Mix different data sources in the same graph! You can specify a data source on a per-query basis. This works for even custom datasources.
