Detailed Description

The InQuery retrieval method for structured queries. Implements the InQuery formulation of idf weighting and default belief value. Behavior can be modified by adjusting that value using the defaultBelief parameter. Provides feedback support in the same fashion as the LEMUR TFIDF method.
