Description

Interface Summary

MultiTermAwareComponent	Add to any analysis factory component to allow returning an analysis component factory for use with partial terms in prefix queries, wildcard queries, range query endpoints, regex queries, etc.
ResourceLoader	Abstraction for loading resources (streams, files, and classes).
ResourceLoaderAware	Interface for a component that needs to be initialized by an implementation of ResourceLoader.

Class Summary

AbstractAnalysisFactory	Abstract parent class for analysis factories TokenizerFactory, TokenFilterFactory and CharFilterFactory.
CharacterUtils	CharacterUtils provides a unified interface to Character-related operations to implement backwards compatible character operations based on a Version instance.
CharacterUtils.CharacterBuffer	A simple IO buffer to use with CharacterUtils.fill(CharacterBuffer, Reader).
CharArrayIterator	A CharacterIterator used internally for use with BreakIterator
CharArrayMap<V>	A simple class that stores key Strings as char[]'s in a hash table.
CharArraySet	A simple class that stores Strings as char[]'s in a hash table.
CharFilterFactory	Abstract parent class for analysis factories that create CharFilter instances.
CharTokenizer	An abstract base class for simple, character-oriented tokenizers.
ClasspathResourceLoader	Simple ResourceLoader that uses ClassLoader.getResourceAsStream(String) and Class.forName(String,boolean,ClassLoader) to open resources and classes, respectively.
ElisionFilter	Removes elisions from a TokenStream.
ElisionFilterFactory	Factory for ElisionFilter.
FilesystemResourceLoader	Simple ResourceLoader that opens resource files from the local file system, optionally resolving against a base directory.
FilteringTokenFilter	Abstract base class for TokenFilters that may remove tokens.
OpenStringBuilder	A StringBuilder that allows one to access the array.
RollingCharBuffer	Acts like a forever growing char[] as you read characters into it from the provided reader, but internally it uses a circular buffer to only hold the characters that haven't been freed yet.
StemmerUtil	Some commonly-used stemming functions
StopwordAnalyzerBase	Base class for Analyzers that need to make use of stopword sets.
TokenFilterFactory	Abstract parent class for analysis factories that create TokenFilter instances.
TokenizerFactory	Abstract parent class for analysis factories that create Tokenizer instances.
WordlistLoader	Loader for text files that represent a list of stopwords.
