Class FieldValueFeature.FieldValueFeatureWeight.DefaultValueFieldValueFeatureScorer

  • Enclosing class:

    public final class FieldValueFeature.FieldValueFeatureWeight.DefaultValueFieldValueFeatureScorer
    extends Feature.FeatureWeight.FeatureScorer
    A FeatureScorer that always returns the default value.

    It is used as a fallback for cases when a segment does not have any documents that contain doc values for a field. By doing so, we prevent a fallback to the FieldValueFeatureScorer, which would also return the default value but in a less performant way because it would first try to read the stored fields for the doc (which aren't present).
