DefaultIRPacket	A description of an information retrieval task.
DropLittleWords	Drops any words of length maximumSize or below (default is three).
FileSearchEngine	This is an implementation of the SearchEngine that uses the FileBTree.
FrequencyVectorCreator	Sets keyword scores based on the frequency of the words.
GeneralVectorCreator	Generates vectors using various standard indexing schemes.
HTMLDocument	A document which can identify HTML Tags and pull out HTML info.
InvertedIndex	Computes and stores an inverted index, which can be used by a search engine.
JDBCVectorCreator	Generates TFIDF vectors from a document set.
OrderVectorCreator	Sets keyword scores based on the order of word occurance.
PagedDocumentSet	A document set backed by an FileObjectPager.
PhraseFrequencyVectorCreator	Sets phrase scores based on the frequency of bigrams.
PorterStemmer	This class implements the Porter stemming algorithm.
PrecisionRecall	A class that performs Precision/Recall testing.
PRPair	The results of a single query for a specific number of documents
PRResult	The results of a PrecisionRecall experiment on a particular query.
PRResultUtils	Utilities for working with PRResult objects.
RAMSearchEngine	An implementation of the SearchEngine interface that keeps all intermediate information in memory.
StopList	Implementation of a simple stoplist.
StreamFreqTable	This class is intended to provide incremental TFIDF information when there is no sense of a "document".
