Abstract

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.

Claims

1. A method for indexing a document comprising:

determining a location associated with the document;

determining a plurality of locations surrounding the location associated with the document; and

indexing the document to include a reference to the location and the plurality of locations surrounding the location.
