Package org.apache.lucene.search

Support for testing search components.

The primary classes are:

• QueryUtils: Useful methods for testing Query classes.
• ShardSearchingTestBase: Base class for simulating distributed search.

Class Summary

Class	Description
AssertingIndexSearcher	Helper class that adds some extra checks to ensure correct usage of IndexSearcher and Weight.
AssertingQuery	Assertion-enabled query.
AssertingScorable	Wraps another Scorable and asserts that scores are reasonable and only called when positioned
AssertingScorer	Wraps a Scorer with additional checks
BaseExplanationTestCase	Tests primitive queries (ie: that rewrite to themselves) to insure they match the expected set of docs, and that the score of each match is equal to the value of the scores explanation.
BaseRangeFieldQueryTestCase	Abstract class to do basic tests for a RangeField query.
BaseRangeFieldQueryTestCase.Range	base class for range verification
BlockScoreQueryWrapper	Query wrapper that reduces the size of max-score blocks to more easily detect problems with the max-score logic.
BulkScorerWrapperScorer	A BulkScorer-backed scorer.
CheckHits	Utility class for asserting expected hits in tests.
CheckHits.ExplanationAsserter	Asserts that the score explanation for every document matching a query corresponds with the true score.
CheckHits.ExplanationAssertingSearcher	an IndexSearcher that implicitly checks hte explanation of every match whenever it executes a search.
CheckHits.MatchesAsserter	Asserts that the Matches from a query is non-null whenever the document its created for is a hit.
CheckHits.SetCollector	Just collects document ids into a set.
MatchesTestBase	Base class for tests checking the Weight.matches(LeafReaderContext, int) implementations
MatchesTestBase.TermMatch	Encapsulates a term position, start and end offset
QueryUtils	Utility class for sanity-checking queries.
RandomApproximationQuery	A Query that adds random approximations to its scorers.
ScorerIndexSearcher	An IndexSearcher that always uses the Scorer API, never BulkScorer.
SearchEquivalenceTestBase	Simple base class for checking search equivalence.
ShardSearchingTestBase	Base test class for simulating distributed search across multiple shards.
ShardSearchingTestBase.SearcherAndVersion	An IndexSearcher and associated version (lease)
