How make a filter "does not contain" in Google Stackdriver logs

Question

In Google Stackdriver advanced filter I can insert something like:

resource.type="container" resource.labels.cluster_name="mycluster" textPayload!="Metric stackdriver_sink_successfully_sent_entry_count was not found in the cache." severity="INFO" textPayload:(helloworld) 

The last rule means that the field textPayload should contain the string helloworld. But I'm not able to find a way to add a NOT operator.

I would use something like:

textPayload:!(helloworld) 

but doesn't work

Answer 1

just add AND NOT between two rows:

resource.type="container" resource.labels.cluster_name="mycluster" textPayload!="Metric stackdriver_sink_successfully_sent_entry_count was not found in the cache." severity="INFO" AND NOT textPayload:(helloworld)
