CA 2593420

A local search engine efficiently indexes documents relevant to a geographical area by indexing, for each document, multiple location identifiers that collectively define an aggregate geographic region. When creating the index, the search engine may determine a set of geographical areas surrounding a geographical area relevant to a document and associate references to the set of geographical areas with the document index.

Selon cette invention, un moteur de recherche local indexe efficacement des documents liés à une zone géographique en indexant, pour chaque document, plusieurs identificateurs de localisation qui définissent collectivement une région géographique d'agrégats. A la création de l'index, le moteur de recherche peut déterminer un ensemble de zones géographiques entourant une zone géographique liée à un document et associer des références à l'ensemble des zones géographiques avec l'index de document.
