Uses of Attribute in org.apache.lucene.search

Subinterfaces of Attribute in org.apache.lucene.search

Modifier and Type	Interface	Description
interface	BoostAttribute	Add this Attribute to a TermsEnum returned by MultiTermQuery.getTermsEnum(Terms,AttributeSource) and update the boost on each returned term.
static interface	FuzzyTermsEnum.LevenshteinAutomataAttribute	reuses compiled automata across different segments, because they are independent of the index
