operatorName property
Indicates the actual string required in the query in order to isolate the date property.
For example, suppose an issue tracking schema object has a property named closeDate that specifies an operator with an operatorName of closedon. For searches on that data, queries like closedon:<value> show results only where the value of the closeDate property 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 indexed datasource. The operator name can only contain lowercase letters (a-z). The maximum length is 32 characters.
Implementation
core.String? operatorName;
