Propose some information retrieval protocols for Internet. Now most services of Internet such as E-mail, BBS, and FTP are all based on public protocol. There is no secret technology in these services. But the information retrieval service, may be the most important service on Internet, is still dominated by few search engine companies. This may not comply with the basic rules of Internet. Some kernel technology, especially the page ranking algorithms, is the top secret of search engine companies. There is no any surveillance in this ranking operation. Some search engines just elevate the ranking score of some pages for the paying of company customer. Every of us publish the information on Internet, but search engines administrate what you could know and what you couldn't reach to a large extent. Someone must pay him money to place their spam in the first place in the search results of everyone. This may not be the truth of Internet. Search engines should be a public mechanism. So there should be some standard protocols to build a real public opening search system for Internet. Some work of our research group may be useful for an appropriate information retrieval protocols for Internet. Our work belongs to a digital library project. The main purpose of our project is to build a search system that can integrate all kinds of information resources on Internet. For this aim, we propose an absolutely new kind of search system,DRIS (domain resource Integrated system). Its main point is as follows. DRIS will build an information retrieval infrastructure for the whole Internet,but not the finial search engines. The basic principle of DRIS: in appropriate scope (three levels domain), applying appropriate information retrieval system, DRIS builds an appropriate information management frame for the whole Internet. The basic idea of DRIS: search should be the internal function of Internet and everyone should have his own search engine.

I think build a public information retrieval system is very important for the evolution of Internet.
