We are developing a search system DAISEn which inte-grates multiple search engines and generates a metasearch engine automatically. The target search engines of DAISEn are not general search engines, but are search engines spe-cialized in some area. Integration of such engines yields efficiency and quality. There are search engines of new type which accept complex query and return structured data. In-tegration of such search engines is much harder than that of simple search engines which accept keywords and return a list of URLs. This paper reports the current situation of complex forms by analyzing 2,880 specialized search engines and demon-strates a possibility to construct metadata for complex query. 1.
