Описание методов

ClearTotalNumberOfTerms() публичный Метод

Expert: Resets the counting of unique terms. Do this before executing the query/filter.

public ClearTotalNumberOfTerms ( ) : void
Результат	void

Equals() публичный Метод

public Equals ( System obj ) : bool
obj	System
Результат	bool

GetEnum() защищенный абстрактный Метод

Construct the enumeration to be used, expanding the pattern term.

protected abstract GetEnum ( Lucene.Net.Index.IndexReader reader ) : Lucene.Net.Search.FilteredTermEnum
reader	Lucene.Net.Index.IndexReader
Результат	Lucene.Net.Search.FilteredTermEnum

GetHashCode() публичный Метод

public GetHashCode ( ) : int
Результат	int

IncTotalNumberOfTerms() защищенный Метод

protected IncTotalNumberOfTerms ( int inc ) : void
inc	int
Результат	void

MultiTermQuery() защищенный Метод

Constructs a query matching terms that cannot be represented with a single Term.

protected MultiTermQuery ( ) : System
Результат	System

Rewrite() публичный Метод

public Rewrite ( Lucene.Net.Index.IndexReader reader ) : Query
reader	Lucene.Net.Index.IndexReader
Результат	Query

Описание свойств

CONSTANT_SCORE_AUTO_REWRITE_DEFAULT публичное статическое свойство

Read-only default instance of ConstantScoreAutoRewrite , with ConstantScoreAutoRewrite.SetTermCountCutoff set to ConstantScoreAutoRewrite.DEFAULT_TERM_COUNT_CUTOFF and ConstantScoreAutoRewrite.SetDocCountPercent set to ConstantScoreAutoRewrite.DEFAULT_DOC_COUNT_PERCENT . Note that you cannot alter the configuration of this instance; you'll need to create a private instance instead.

public static RewriteMethod,Lucene.Net.Search CONSTANT_SCORE_AUTO_REWRITE_DEFAULT
Результат	RewriteMethod

CONSTANT_SCORE_BOOLEAN_QUERY_REWRITE публичное статическое свойство

Like SCORING_BOOLEAN_QUERY_REWRITE except scores are not computed. Instead, each matching document receives a constant score equal to the query's boost.

NOTE: This rewrite method will hit BooleanQuery.TooManyClauses if the number of terms exceeds BooleanQuery.GetMaxClauseCount.

Результат	RewriteMethod

CONSTANT_SCORE_FILTER_REWRITE публичное статическое свойство

A rewrite method that first creates a private Filter, by visiting each term in sequence and marking all docs for that term. Matching documents are assigned a constant score equal to the query's boost.

This method is faster than the BooleanQuery rewrite methods when the number of matched terms or matched documents is non-trivial. Also, it will never hit an errant BooleanQuery.TooManyClauses exception.

Результат	RewriteMethod

SCORING_BOOLEAN_QUERY_REWRITE публичное статическое свойство

A rewrite method that first translates each term into Occur.SHOULD clause in a BooleanQuery, and keeps the scores as computed by the query. Note that typically such scores are meaningless to the user, and require non-trivial CPU to compute, so it's almost always better to use CONSTANT_SCORE_AUTO_REWRITE_DEFAULT instead.

NOTE: This rewrite method will hit BooleanQuery.TooManyClauses if the number of terms exceeds BooleanQuery.GetMaxClauseCount.
