The Search Broker
The current search facilities on the web are amazingly powerful, but they are still lacking. Taking the whole universe as one flat data space and searching it with keywords has inherent limitations of scale. The challenge is to provide users with ways to focus their search better without making it too difficult or too inefficient. We introduce a method of conducting search on the web that is based on a two-level search idea. It strikes a balance between flat global search and specialized databases, and gives users convenient access to vast amounts of information.
