[]

Scalar consensus

The scalar consensus applies for implementations which return a single value where only one match is possible (instead of an array of a single value).

null

Not found consensus

This consensus applies for implementations which return a specific not found value if no match exists.

NOT_FOUND

Scalar not found consensus

This consensus applies for implementations which returns a specific not found value when a query that would regularly return a single match results in no match.
