ABSTRACT:
A system and method for scoring documents in a search, wherein the scoring algorithm may be reconfigured dynamically. When a query is submitted, a score data structure is created for each document to be scored, which contains fields of information about how a given document compares to a query. A ranker object embodies a formula that derives a scalar score from the information contained in a score data structure. Scoring software is configured to apply the formula embodied in a ranker object to the values in the score data structure. Thus, the scoring formula can be dynamically changed without recompiling the scoring software by providing a new ranker object. Preferably, ranker objects are organized into rank sets, where each rank set contains a different ranker object for each class of document to be scored.
