I have query regarding Data models base search
| multisearch [| from datamodel:Endpoint.Filesystem | search tag="change" ] [| from datamodel:Endpoint.Registry | search tag="change" ] [| from datamodel:Change.Endpoint_Changes | search ] | head 100
Above is the query for "Recent Endpoint Changes" in Endpoint Changes Dashboard (Splunk Enterprise Security (Endpoint Security Domain))
Now query refers to Endpoint.Filesystem data model. This data model includes cim_Endpoint_indexes macros which refers to index=crowstrike in my environment and 2 tags as tag=filesystem and tag=endpoint. These tags are filled with eventtypes where sourcetypes are specified. Now one of the eventtype refers to sourcetype as aws:cloudtrail.
And whatever result i am getting for above query is related to aws:cloudtrail only.
Now my understanding is when you are referring to data model in your query then it should gives you results from specified index and in this case index=crowdstrike sourcetype=aws:cloudtrail is invalid but still above search is populating results in dashboard
In short data models base search is not fulfilling the specified fields but still results are getting populated
