Abstract
A method and system for determining relevance of a document to a query based on identifier match distance is provided. The relevance system analyzes a training set of queries and documents to determine the relationship between identifier match distance and relevance of a document to a query. The identifier match distance indicates the distance from the end of an identifier of a document to an identifier term that matches a query term. The relevance system generates a prior relevance probability that a document with a certain identifier match distance is relevant to a query. The relevance system uses the prior relevance probabilities to determine relevance of documents to queries based on identifier match distance.
