Interface MaxNonCompetitiveBoostAttribute
- All Superinterfaces:
Attribute
- All Known Implementing Classes:
MaxNonCompetitiveBoostAttributeImpl
Add this
Attribute to a fresh AttributeSource before calling MultiTermQuery.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 empty AttributeSource that is shared for all segments
during query rewrite. This attribute source is passed to all segment enums on MultiTermQuery.getTermsEnum(Terms,AttributeSource). TopTermsRewrite uses this attribute
to inform all enums about the current boost, that is not competitive.
- NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

Method Details
-
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
This is the term ornullof the term that triggered the boost change. -
getCompetitiveTerm
BytesRef getCompetitiveTerm()This is the term ornullof the term that triggered the boost change. Default isnull, which means every term is competitoive.
