With Splunk HEC it is possible to send a HTTP POST with Json payload to services/collector/event . This supports the fields Json key, that enables you to add additional data to an event that is not present in the _raw (or event) data.
Given the following json payload you should be able to search search index=* k8s_node="node01*" :
{ "event": "datadata", "fields": {"k8s_node":"node01.domain.tld", "k8s_namespace","namespacename"}}
However when searching for fields that are not present in the _raw data, the search will not give you a match, and you will not be able to match searches to the items in the fields key.
What could be done to resolve this?
