Interface for all Matching implementations.
This interface encapsulates all the common functionality between standard IR models (including DFR models, TF/IDF, BM25 etc), and Language Modelling models (Terrier includes PonteCroft Language Modelling model).
Interface for plugins to further alter the posting lists managed by the PostingListManager
The interface that defines the functionalities of a result set.

Performs the matching of documents with a query, by first assigning scores to documents for each query term and modifying these scores with the appropriate modifiers.
This class implements the interface ResultSet and models the set of all documents in the collection.

A result set for a given query.
A matching implementation that retrieves results from a TREC result file rather than the current index.
The result set input format.
Provides the classes and interfaces used for matching documents to queries. It includes the classes that perform the matching by reading information from the inverted index etc., and the classes that model the set of retrieved documents.
