checkNoMatchExplanations
public static void checkNoMatchExplanations(Query q, String defaultFieldName, IndexSearcher searcher, int[] results) throws IOException
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- Throws:
IOException
-
checkHitCollector
public static void checkHitCollector(Random random, Query query, String defaultFieldName, IndexSearcher searcher, int[] results) throws IOException
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.
- Parameters:
query
- the query to testsearcher
- the searcher to test the query againstdefaultFieldName
- used for displaying the query in assertion messagesresults
- a list of documentIds that must match the query- Throws:
IOException
- See Also:
checkHits(java.util.Random, org.apache.lucene.search.Query, java.lang.String, org.apache.lucene.search.IndexSearcher, int[])
-
checkHits
public static void checkHits(Random random, Query query, String defaultFieldName, IndexSearcher searcher, int[] results) throws IOException
Tests that a query matches the 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.
- Parameters:
query
- the query to testsearcher
- the searcher to test the query againstdefaultFieldName
- used for displaing the query in assertion messagesresults
- a list of documentIds that must match the query- Throws:
IOException
- See Also:
checkHitCollector(java.util.Random, org.apache.lucene.search.Query, java.lang.String, org.apache.lucene.search.IndexSearcher, int[])
-
checkDocIds
public static void checkDocIds(String mes, int[] results, ScoreDoc[] hits)
Tests that a Hits has an expected order of documents
-
checkHitsQuery
public static void checkHitsQuery(Query query, ScoreDoc[] hits1, ScoreDoc[] hits2, int[] results)
Tests that two queries have an expected order of documents, and that the two queries have the same score values.
-
checkExplanations
