Public Methods

Method	Description
Explain ( Lucene.Net.Index.IndexReader reader, int doc ) : Explanation	An explanation of the score computation for the named document.
Normalize ( float norm ) : void	Assigns the query normalization factor to this.
Scorer ( Lucene.Net.Index.IndexReader reader, bool scoreDocsInOrder, bool topScorer ) : Lucene.Net.Search.Scorer	Returns a Scorer which scores documents in/out-of order according to `scoreDocsInOrder`. NOTE: even if `scoreDocsInOrder` is false, it is recommended to check whether the returned `Scorer` indeed scores documents out of order (i.e., call ScoresDocsOutOfOrder()), as some `Scorer` implementations will always return documents in-order. NOTE: null can be returned if no documents will be scored by this query.

Method Details

Explain() public abstract method

An explanation of the score computation for the named document.

public abstract Explain ( Lucene.Net.Index.IndexReader reader, int doc ) : Explanation
reader	Lucene.Net.Index.IndexReader	sub-reader containing the give doc ///
doc	int	///
return	Explanation

Normalize() public abstract method

Assigns the query normalization factor to this.

public abstract Normalize ( float norm ) : void
norm	float
return	void

Scorer() public abstract method

Returns a Scorer which scores documents in/out-of order according to scoreDocsInOrder.

NOTE: even if scoreDocsInOrder is false, it is recommended to check whether the returned Scorer indeed scores documents out of order (i.e., call ScoresDocsOutOfOrder()), as some Scorer implementations will always return documents in-order.
NOTE: null can be returned if no documents will be scored by this query.

scoreDocsInOrder	bool	specifies whether in-order scoring of documents is required. Note /// that if set to false (i.e., out-of-order scoring is required), /// this method can return whatever scoring mode it supports, as every /// in-order scorer is also an out-of-order one.
