Abstract: This invention provides a context-aware search engine that communicates with users having a particular location at a particular time within a tessellated network of geographically spaced-apart communication nodes, typically wireless nodes/access points (APs). Based upon the user's location and time, the search engine delivers relevant site-specific information germane to that user's place and time. In an illustrative embodiment, the search engine correlates the address of the node within which the user is located when making a query to the engine via a wireless device such as a laptop computer, PDA or cellular telephone. The time of the query is also accounted for. The query causes the search engine to focus its database search (from a large array of information resources indexed by the search engine and accessible thereby) on those informational items/web sites that fit the appropriate place and time of the user.
