+Our sink here will be Quickwit ingest API `http://127.0.0.1:7280/api/v1/otel-logs-v0_7/ingest`.
 To keep it simple in this tutorial, we will use a log source called `demo_logs` that generates logs in a given format. Let's choose the common `syslog` format
 (Vector does not generate logs in the OpenTelemetry format directly!) and use the transform feature to map the `syslog` format into the OpenTelemetry format.

 ## Search logs
 
 Quickwit is now ingesting logs coming from Vector and you can search them either with `curl` or by using the UI:
-- `curl -XGET http://127.0.0.1:7280/api/v1/otel-logs-v0_6/search?query=severity_text:ERROR`
-- Open your browser at `http://127.0.0.1:7280/ui/search?query=severity_text:ERROR&index_id=otel-logs-v0_6&max_hits=10` and play with it!
