Another way of increasing the relevance of a search is by limiting its scope.
Toronto-based Lasoo limits the scope of searches geographically, by asking users to select an area on an electronic map using a circular "lasso."
Unlike Google, Lasoo looks for information -- such as businesses and jobs –- only in the selected geographic area.
Lasoo selects results according to their physical proximity to the "epicenter" chosen by the user. It doesn't follow administrative or political divisions. Results are displayed on a map.
"We have a high-speed map server technology that allows us to create detailed maps for the entire world," says Peter Forth, Lasoo's chief technology officer. "And we have a geographic search engine technology that sifts through a database of over 30 million geo-coded businesses to find entries that match a particular keyword and are in a specific geographic area."
According to Forth, most other geographical search engines such as Yahoo are focused on the United States or on major cities only, whereas Lasoo is worldwide.
