Range filters can be applied to either standard attributes or managed attributes of the following supported types.
For values of attributes of type Double, you can specify values using both decimal (0.00...68), and scientific notation (6.8e-10).
For standard attributes of type Boolean, false is interpreted to be less than true. If isOdd is a Boolean attribute, a query of isOdd|LTEQ false will return all records with assignments of false on attribute isOdd. Likewise, isOdd|BTWN false true will return all records with any assignment on isOdd.
No Dgraph process configuration flags are necessary to enable range filters. All numeric standard attributes and managed attributes and all geocode standard attributes are automatically enabled for use in range filters.
