Class FacetRefinement (2.0.0)

public final class FacetRefinement

A Facet Refinement to filter out search results based on a facet value.

We recommend using refinement token strings instead of this class. We include a refinement token string with each FacetResultValue returned by the backend that can be passed to Query.Builder#addFacetRefinementFromToken(String) to refine follow-up queries.

We also support manually-specified query refinements by passing an instance of this class to Query.Builder#addFacetRefinement(FacetRefinement).

Example: Request to only return documents that have a number facet named "rating" with a value between one and two:


 FacetRefinement lowRating = FacetRefinement.withRange("rating", FacetRange.startEnd(1.0, 2.0));
 query.addFacetRefinement(lowRating);
