Different search results via GUI/REST API

If you constrain your API call to the All Messages Stream, what do you get? - I have little experience with the API but based on Jan Doberstein’s post here, it seems you could add the stream as below…

curl -i -X POST \
-u 'EventReader:TQlCyGdrrlWuhNVy2sKM' \
-H 'Content-Type: application/json' \
-H 'Accept: text/csv' \
-H 'X-Requested-By: cli' \
'http://graylog.xxx.xxx:9000/api/views/search/messages' -d \
'{ 
 "streams": [
    "<stream-ID-Here>"
  ],
"timerange": [
    "absolute",{
      "from": "2021-12-22T00:00:00.000Z",
      "to": "2021-12-23T18:55:00.000Z"
    }
  ],
  "fields_in_order": [
    "timestamp",
    "ObjectName", 
    "SubjectUserName"
  ]
 }'
