Public Methods

Method	Description
Check ( Query q ) : void	Check the types of things query objects should be able to do.
Check ( Random random, Query q1, IndexSearcher s, Similarity similarity ) : void	Various query sanity checks on a searcher, some checks are only done for instanceof IndexSearcher.
Check ( Random random, Query q1, IndexSearcher s, bool wrap, Similarity similarity ) : void
CheckEqual ( Query q1, Query q2 ) : void
CheckExplanations ( Query q, IndexSearcher s ) : void	deep check that explanations of a query 'score' correctly
CheckFirstSkipTo ( Query q, IndexSearcher s, Similarity similarity ) : void	check that first skip on just created scorers always goes to the right doc
CheckHashEquals ( Query q ) : void	check very basic hashCode and equals
CheckSkipTo ( Query q, IndexSearcher s, Similarity similarity ) : void	alternate scorer skipTo(),skipTo(),next(),next(),skipTo(),skipTo(), etc and ensure a hitcollector receives same docs and scores
CheckUnequal ( Query q1, Query q2 ) : void
PurgeFieldCache ( IndexReader r ) : void
WrapUnderlyingReader ( Random random, IndexSearcher s, int edge, Similarity similarity ) : IndexSearcher	Given an IndexSearcher, returns a new IndexSearcher whose IndexReader is a MultiReader containing the Reader of the original IndexSearcher, as well as several "empty" IndexReaders -- some of which will have deleted documents in them. this new IndexSearcher should behave exactly the same as the original IndexSearcher.

Method Details

Check() public static method

Check the types of things query objects should be able to do.

public static Check ( Query q ) : void
q	Query
return	void

Check() public static method

Various query sanity checks on a searcher, some checks are only done for instanceof IndexSearcher.

public static Check ( Random random, Query q1, IndexSearcher s, Similarity similarity ) : void
random	System.Random
q1	Query
s	IndexSearcher
similarity	Similarity	/// LUCENENET specific /// Removes dependency on ///
return	void

Check() public static method

public static Check ( Random random, Query q1, IndexSearcher s, bool wrap, Similarity similarity ) : void
random	System.Random
q1	Query
s	IndexSearcher
wrap	bool
similarity	Similarity	/// LUCENENET specific /// Removes dependency on ///
return	void

CheckEqual() public static method

public static CheckEqual ( Query q1, Query q2 ) : void
q1	Query
q2	Query
return	void

CheckExplanations() public static method

deep check that explanations of a query 'score' correctly

public static CheckExplanations ( Query q, IndexSearcher s ) : void
q	Query
s	IndexSearcher
return	void

CheckFirstSkipTo() public static method

check that first skip on just created scorers always goes to the right doc

public static CheckFirstSkipTo ( Query q, IndexSearcher s, Similarity similarity ) : void
q	Query
s	IndexSearcher
similarity	Similarity	/// LUCENENET specific /// Removes dependency on ///
return	void

CheckHashEquals() public static method

check very basic hashCode and equals

public static CheckHashEquals ( Query q ) : void
q	Query
return	void

CheckSkipTo() public static method

alternate scorer skipTo(),skipTo(),next(),next(),skipTo(),skipTo(), etc and ensure a hitcollector receives same docs and scores

public static CheckSkipTo ( Query q, IndexSearcher s, Similarity similarity ) : void
q	Query
s	IndexSearcher
similarity	Similarity	/// LUCENENET specific /// Removes dependency on ///
return	void

CheckUnequal() public static method

public static CheckUnequal ( Query q1, Query q2 ) : void
q1	Query
q2	Query
return	void

PurgeFieldCache() public static method

public static PurgeFieldCache ( IndexReader r ) : void
r	IndexReader
return	void

WrapUnderlyingReader() public static method

Given an IndexSearcher, returns a new IndexSearcher whose IndexReader is a MultiReader containing the Reader of the original IndexSearcher, as well as several "empty" IndexReaders -- some of which will have deleted documents in them. this new IndexSearcher should behave exactly the same as the original IndexSearcher.

public static WrapUnderlyingReader ( Random random, IndexSearcher s, int edge, Similarity similarity ) : IndexSearcher
random	System.Random
s	IndexSearcher	the searcher to wrap
edge	int	if negative, s will be the first sub; if 0, s will be in the middle, if positive s will be the last sub
similarity	Similarity	/// LUCENENET specific /// Removes dependency on ///
return	IndexSearcher
