operatorName property
The operator_name applied to the query, such as price_greater_than.
The filter can work against both types of filters defined in the schema
for your data source: 1. operator_name, where the query filters results
by the property that matches the value. 2. greater_than_operator_name or
less_than_operator_name in your schema. The query filters the results
for the property values that are greater than or less than the supplied
value in the query.
Implementation
core.String? operatorName;
