The Grafana plugin does not support regular expression matching for dropdown boxes.

Describe the bug

To Reproduce

Why is it only allowed to write regular expressions in code? Actually, I only need simple regular expressions, such as: kubernetes.pod_node_name: "hgx-012" OR kubernetes.pod_name:~ "envoy-ai-gateway-v0.". This cannot be achieved in the plugin's builder. The key point is this statement: kubernetes.pod_name:~ "envoy-ai-gateway-v0.". The Loki plugin supports this, but VL cannot use it in Grafana through the Loki plugin. It's a pity~

@ZYWNB666 Thanks for reporting the issue! Right now, we are working on improving the query builder. So I suppose this problem could be fixed in the #578 .

Hello, I am migrating from Loki to VictoriaLogs. Currently, VictoriaLogs is not as user-friendly as Loki when used in Grafana. Could you please add a Label browser for VictoriaLogs like Loki does, as well as add filter text highlighting for VictoriaLogs? Thank you.

Hello, thanks for the feature suggestion!
Did you try Stream filters in the VictoriaLogs datasource?

I think it should cover user cases related to label browsing. You can try it on our playground

Thank you for providing the Stream filters feature. It is indeed very convenient for daily searches. However, its usability is still not as good as Loki's Label browser. As shown in the figure, there are many labels in the logs. In Loki, I can select multiple labels, and the search will match all selected labels. Moreover, when I open the Label browser again later, it remembers the labels I previously selected.

Could you please describe your most frequently used daily use cases?
It's needed to understand how we can improve our interface.

I have deployed two logging systems: Loki and VictoriaLogs. Since VictoriaLogs is not as user‑friendly as Loki when it comes to label filtering, I still prefer to use Loki for log retrieval when troubleshooting system issues. I have been hoping to fully switch to VictoriaLogs once its log retrieval interface becomes more friendly.

In my daily troubleshooting of application failures, my log retrieval in Grafana heavily depends on label filtering. As shown in the figure, in Loki's Label browser I usually select several labels to filter. When I select, for example, system, the other labels (like app, job, module, etc.) are dynamically filtered and displayed accordingly. Although VictoriaLogs' Stream filters have greatly improved label filtering compared to before, they are still not as easy to use as Loki's Label browser.

Moreover, when I open a new query tab, Loki's Label browser remembers the labels I selected. When I open it again, I don't need to re‑select labels unless necessary.

Loki's log search highlighting is also very useful. Highlighting the searched keywords allows me to quickly spot critical information from a large volume of logs.
