          org.apache.lucene.search.SearchEquivalenceTestBase

public abstract class SearchEquivalenceTestBase
extends LuceneTestCase

Simple base class for checking search equivalence. Extend it, and write tests that create randomTerm()s (all terms are single characters a-z), and use assertSameSet(Query, Query) and assertSubsetOf(Query, Query)
