To check if a field is not available use exists and a dash in front of it: -exists (not exists)
This functionality is similar to the NOT Filter with the Exists Filter
Find the fieldpath of the field you are looking for: layerId.fieldId
The syntax is based on Elastic Search Boolean Operator Logic: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#_boolean_operators
