Class Summary

Class	Description
AbstractAnalyzerFactoryTest
AbstractDefaultAnalyzerFactoryTest
AbstractIndexTask<V extends Comparable<V>>	Set up the from and to keys for the ReadIndexTask and CountIndexTask.
AbstractSearchTest
ConfigurableAnalyzerFactory	This class can be used with the bigdata properties file to specify which Analyzers are used for which languages.
CountIndexTask<V extends Comparable<V>>	Procedure reads on the terms index, aggregating data on a per-Hit basis.
DefaultAnalyzerFactory	Deprecated Using ConfigurableAnalyzerFactory with the ConfigurableAnalyzerFactory.Options.NATURAL_LANGUAGE_SUPPORT uses the appropriate natural language analyzers for the two letter codes and for tags which include sub-tags.
EmptyAnalyzer	An analyzer that always returns an EmptyTokenStream, this can be used with ConfigurableAnalyzerFactory to switch off indexing and searching for specific language tags.
FullTextIndex<V extends Comparable<V>>	Full text indexing and search support.
FullTextIndexTupleSerializer<V extends Comparable<V>>	Class manages the encoding and decoding of keys for the full text index.
Hit<V extends Comparable<V>>	Metadata about a search result.
Hiterator<A extends IHit>	Visits search results in order of decreasing relevance.
LanguageRange	This is an implementation of RFC 4647 language range, targetted at the specific needs within bigdata, and only supporting the extended filtering specified in section 3.3.2
MultiTokenHitCollector<V extends Comparable<V>>	Multi-token implementation of IHitCollector backed by a ConcurrentHashMap.
NonEnglishExamples
ReadIndexTask<V extends Comparable<V>>	Procedure reads on the terms index, aggregating data on a per-Hit basis.
ReadOnlyTermDocKey<V extends Comparable<V>>	Read-only ITermDocKey.
ReadOnlyTermDocRecord<V extends Comparable<V>>	Read-only ITermDocRecord.
SingleTokenHitCollector<V extends Comparable<V>>	Single-token implementation of IHitCollector backed by a simple array of hits.
TermCompletionAnalyzer	An analyzer intended for the term-completion use case; particularly for technical vocabularies and concept schemes.
TermFrequencyData<V extends Comparable<V>>	Models the term-frequency data associated with a single field of some document.
TermMetadata	Mutable metadata for the occurrences of a term within a field of some document.
TestAll
TestConfigurableAnalyzerFactory	Unit tests for ConfigurableAnalyzerFactory.
TestConfigurableAnalyzerFactory.NoStopWordsAnalyzer
TestConfigurableAsDefaultAnalyzerFactory
TestDefaultAnalyzerFactory
TestKeyBuilder	Unit tests for key formation for the FullTextIndex.
TestLanguageRange
TestPrefixSearch	Unit test for prefix and exact match searches.
TestSearch	Test suite using examples based on Understanding Search Engines by Barry and Browne.
TestSearchRestartSafe	Simple test verifies that the FullTextIndex data are restart safe.
TestUnconfiguredAnalyzerFactory
TextIndexWriteProc	Writes on the text index.
TextIndexWriteProc.IndexWriteProcConstructor
TokenBuffer<V extends Comparable<V>>	A buffer holding tokens extracted from one or more documents / fields.
