These are the simplest RQL queries, in which a property’s value is compared against another property value, or against a constant. For example:
age > 30
All of the standard comparison operators can be used: =, !=, <, <=, >, >=. These operators can even be applied to String properties and arguments, in which case ordering is determined by lexical order of the Strings.
In general, these operators can only be used on properties that are scalar values. They shouldn’t be used on properties that are array or collection values.
