Detailed Description

Abstract interface for retrieval function with a default implementation (dot product).

This is an abstract interface for a retrieval function that can be written as involving a sum over all the matched terms between a query and a document. Many retrieval functions can be rewritten in this form. Please see the API documentation on the Lemur web site for more information about the generic scoring function form.
