+When you configure this filter to point to an {es} cluster, it detects which ingest pipeline (if any) should be executed for each event,
 using an explicitly-defined <<plugins-{type}s-{plugin}-pipeline_name>> or auto-detecting the event's data-stream and its default pipeline.
 
-It will then load that pipeline's definition from {es} and run that pipeline inside Logstash without transmitting the event to {es}.
