public interface MaxNonCompetitiveBoostAttribute extends Attribute
Add thisAttribute
to a freshAttributeSource
before callingMultiTermQuery.getTermsEnum(Terms,AttributeSource)
.FuzzyQuery
is using this to control its internal behaviour to only return competitive terms.Please note: This attribute is intended to be added by the
MultiTermQuery.RewriteMethod
to an emptyAttributeSource
that is shared for all segments during query rewrite. This attribute source is passed to all segment enums onMultiTermQuery.getTermsEnum(Terms,AttributeSource)
.TopTermsRewrite
uses this attribute to inform all enums about the current boost, that is not competitive.

Method Detail
-
setMaxNonCompetitiveBoost
void setMaxNonCompetitiveBoost(float maxNonCompetitiveBoost)
This is the maximum boost that would not be competitive.
-
getMaxNonCompetitiveBoost
float getMaxNonCompetitiveBoost()
This is the maximum boost that would not be competitive. Default is negative infinity, which means every term is competitive.
-
setCompetitiveTerm
void setCompetitiveTerm(BytesRef competitiveTerm)
This is the term ornull
of the term that triggered the boost change.
-
getCompetitiveTerm
BytesRef getCompetitiveTerm()
This is the term ornull
of the term that triggered the boost change. Default isnull
, which means every term is competitoive.
