Methodologies are provided which use affinity lists in order to perform query retrieval more effectively and efficiently. The invention comprises a two phase method. In the first phase, we find a threshold numberk of candidate documents which are retrieved by the method. In the second phase, we calculate the affinity value to each of these k documents and report them in ranked order of affinities. The first phase of finding the k most valuable candidates is accomplished using an iterative technique on the affinity lists. Once these candidates have been found, the affinity to each document in t
