Abstract This paper introduces research on vertical search engines, analyzes its features and applications comparing with general search engines. Practical problems such as improving precision ratio, searching speed, information acquisition efficiency and controlling information acquisition quality are also discussed. With the catering vertical search prototype in 12580 information acquisition system as a reference, some application strategies about information acquisition, information updates and information extraction are proposed.
