greaterThanOperatorName property
Indicates the operator name required in the query in order to isolate the timestamp property using the greater-than operator.
For example, if greaterThanOperatorName is closedafter and the property's name is closeDate, then queries like closedafter:<value> show results only where the value of the property named closeDate is later than <value>. The operator name can only contain lowercase letters (a-z). The maximum length is 32 characters.
Implementation
core.String? greaterThanOperatorName;
