operatorName property
Indicates the operator name required in the query in order to isolate the enum property.
For example, if operatorName is priority and the property's name is priorityVal, then queries like priority:<value> show results only where the value of the property named priorityVal 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;
