Example (Equality):

description: "Determines if requestor is the document owner"
expression: "document.owner == request.auth.claims.email"
Example (Logic):
title: "Public documents"
description: "Determine whether the document should be publicly visible"
expression: "document.type != 'private' && document.type != 'internal'"
Example (Data Manipulation):
title: "Notification string"
description: "Create a notification string with a timestamp."
expression: "'New message received at ' + string(document.create_time)"
The exact variables and functions that may be referenced within an expression are determined by the service that evaluates it. See the service documentation for additional information.
