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.
