operatorName property
Indicates the operator name required in the query in order to isolate the boolean property.
For example, if operatorName is closed and the property's name is isClosed, then queries like closed:<value> show results only where the value of the property named isClosed matches <value>. By contrast, a search that uses the same <value> without an operator returns all items where <value> matches the value of any String properties or text within the content field for the item. The operator name can only contain lowercase letters (a-z). The maximum length is 32 characters.
Implementation
core.String? operatorName;
