Scope  (4)

Some properties allow you to specify dates:

Some properties allow you to specify dates and locations:

Date qualifiers can accept an explicit DateObject or queries that evaluate to a DateObject:

Location qualifiers can accept an explicit GeoPosition, location-based Entity objects, or queries that evaluate to one of these:
