Class CheckHits

Utility class for asserting expected hits in tests.

Inheritance

System.Object

CheckHits

Namespace: Lucene.Net.Search

Assembly: Lucene.Net.TestFramework.dll

Syntax

public static class CheckHits : object

Fields

EXPLAIN_SCORE_TOLERANCE_DELTA

Some explains methods calculate their values though a slightly different order of operations from the actual scoring method ... this allows for a small amount of relative variation

Declaration

public static float EXPLAIN_SCORE_TOLERANCE_DELTA

Field Value

Type	Description
System.Single

EXPLAIN_SCORE_TOLERANCE_MINIMUM

In general we use a relative epsilon, but some tests do crazy things like boost documents with 0, creating tiny tiny scores where the relative difference is large but the absolute difference is tiny. we ensure the the epsilon is always at least this big.

Declaration

public static float EXPLAIN_SCORE_TOLERANCE_MINIMUM

Field Value

Type	Description
System.Single

Methods

CheckDocIds(String, Int32[], ScoreDoc[])

Tests that a Hits has an expected order of documents.

Declaration

public static void CheckDocIds(string mes, int[] results, ScoreDoc[] hits)

Parameters

Type	Name	Description
System.String	mes
System.Int32[]	results
ScoreDoc[]	hits

CheckEqual(Query, ScoreDoc[], ScoreDoc[])

Declaration

public static void CheckEqual(Query query, ScoreDoc[] hits1, ScoreDoc[] hits2)

Parameters

Type	Name	Description
Query	query
ScoreDoc[]	hits1
ScoreDoc[]	hits2

CheckExplanations(Query, String, IndexSearcher)

Asserts that the explanation value for every document matching a query corresponds with the true score.

See for a "deep" testing of the explanation details.

Declaration

public static void CheckExplanations(Query query, string defaultFieldName, IndexSearcher searcher)

Parameters

Type	Name	Description
Query	query	The query to test.
System.String	defaultFieldName	Used for displaing the query in assertion messages.
IndexSearcher	searcher	The searcher to test the query against.

ExplanationAsserter

CheckExplanations(Query, String, IndexSearcher, Boolean)

Asserts that the explanation value for every document matching a query corresponds with the true score. Optionally does "deep" testing of the explanation details.

Declaration

public static void CheckExplanations(Query query, string defaultFieldName, IndexSearcher searcher, bool deep)

Parameters

Type	Name	Description
Query	query	The query to test.
System.String	defaultFieldName	Used for displaing the query in assertion messages.
IndexSearcher	searcher	The searcher to test the query against.
System.Boolean	deep	Indicates whether a deep comparison of sub-Explanation details should be executed.

CheckHitCollector(Random, Query, String, IndexSearcher, Int32[])

Tests that a query matches the an expected set of documents using a HitCollector.

Note that when using the HitCollector API, documents will be collected if they "match" regardless of what their score is.

Declaration

public static void CheckHitCollector(Random random, Query query, string defaultFieldName, IndexSearcher searcher, int[] results)

Parameters

Type	Name	Description
Random	random
Query	query	The query to test.
System.String	defaultFieldName	Used for displaying the query in assertion messages.
IndexSearcher	searcher	The searcher to test the query against.
System.Int32[]	results	A list of documentIds that must match the query.

DoCheckHits(Random, Query, String, IndexSearcher, Int32[])

CheckHitsQuery(Query, ScoreDoc[], ScoreDoc[], Int32[])

Tests that two queries have an expected order of documents, and that the two queries have the same score values.

Declaration

public static void CheckHitsQuery(Query query, ScoreDoc[] hits1, ScoreDoc[] hits2, int[] results)

Parameters

Type	Name	Description
Query	query
ScoreDoc[]	hits1
ScoreDoc[]	hits2
System.Int32[]	results

CheckNoMatchExplanations(Query, String, IndexSearcher, Int32[])

Tests that all documents up to maxDoc which are not in the expected result set, have an explanation which indicates that the document does not match

Declaration

public static void CheckNoMatchExplanations(Query q, string defaultFieldName, IndexSearcher searcher, int[] results)

Parameters

Type	Name	Description
Query	q
System.String	defaultFieldName
IndexSearcher	searcher
System.Int32[]	results

DoCheckHits(Random, Query, String, IndexSearcher, Int32[])

Tests that a query matches the an expected set of documents using Hits.

Note that when using the Hits API, documents will only be returned if they have a positive normalized score.

Declaration

public static void DoCheckHits(Random random, Query query, string defaultFieldName, IndexSearcher searcher, int[] results)

Parameters

Type	Name	Description
Random	random
Query	query	the query to test
System.String	defaultFieldName	used for displaing the query in assertion messages
IndexSearcher	searcher	the searcher to test the query against
System.Int32[]	results	a list of documentIds that must match the query

Returns
