Range filter queries

The EQL range filter functionality allows a user, at request time, to specify either a literal value or a geocode value to limit the records returned for the query.

The remaining refinement dimension values for the records in the result set are also returned. The literal value expressions are called basic range queries and the geocode value expressions are geospatial range queries.

Note: Do not confuse EQL range filters with the range filters implemented by the Nf parameter. Although both types of range filters are similar in nature, EQL range filters are implemented differently, as described below.
