Interface IBoostAttribute

Add this IAttribute to a TermsEnum returned by GetTermsEnum(Terms, AttributeSource) and update the boost on each returned term. This enables to control the boost factor for each matching term in SCORING_BOOLEAN_QUERY_REWRITE or TopTermsRewrite<Q> 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.
