Abstract: Web search engine plays an important role in searching useful information. And topic-specific search engines can return far better results than standard search engines. However, it is difficult for the casual user to identify the appropriate topic-specific search engine for any given query. It is very convenient for them to issue their queries at a particular website, and have the queries automatically routed to these search engines. This paper presents such a query routing system.
