## Interface BoostAttribute

All Superinterfaces:
  Attribute

All Known Implementing Classes:
  BoostAttributeImpl

    public interface BoostAttribute
    extends Attribute

Add this `Attribute` to a `TermsEnum` returned by `MultiTermQuery.getTermsEnum(Terms,AttributeSource)` and update the boost on each returned term. This enables to control the boost factor for each matching term in `MultiTermQuery.SCORING_BOOLEAN_QUERY_REWRITE` or `TopTermsRewrite` mode. `FuzzyQuery` is using this to take the edit distance into account.

Please note: This attribute is intended to be added only by the TermsEnum to itself in its constructor and consumed by the `MultiTermQuery.RewriteMethod`.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.
