SEARCHING AND RANKING CONTACTS IN A CONTACT DATABASE

摘要

In one aspect, a method may include receiving a request from a first mobile device for a search for contacts meeting a criterion; searching a database of contacts for the contacts meeting the criterion and including the contacts meeting the criterion in search results; determining whether a second mobile device associated with one of the contacts meeting the criterion is within a vicinity of the first mobile device; and ranking the search results based on the determination. In another aspect, the method may further include determining a database distance between a reference contact and each of one or more of the search results, where the request is associated with a reference contact in the database of contacts; and ranking the search results based on the determined database distance; where the database of contacts may include a plurality of subsets of contacts, where contacts in the subsets are linked to another contact in the database of contacts; where determining a database distance between the reference contact and each of the one or more of the search results may include determining the number of links between the reference contact and each of one or more of the search results.
