Search Engineer: Researching The Resource Search Arithmetic About FTP And Others Protocol

Today Search Engineer becomes the most import assistant, with the growing of Internet. Scientific research organization attaches importance to the research on Search Engine Technology. Beijing University of Chemical Technology bring the research on Search Engine Technology into sub-project of the 211 Project. It is the most import part of this project, which this paper research content "Search Engineer: researching the resource search arithmetic about ftp and others protocol".Studied the FTP Search Engine technology, acquired the knowledge of FTP protocol, and analyzed search theory about FTP protocol resource. Designed and developed FSearch system on base of this work. This system is self developed and face the campus people. Apply lots of technology, such as .NET, XML, C#, Database, Network and so on, in the course of developing system. The FSearch Search Engineer system provide user interface which support complex search, and completed host snap function. Now, system has completed testing, and using in Beijing University of Chemical Technology. Studied the peer to peer protocol. Analyzed four typical peer to peer system topology, and found out the characteristic of this topology. On this base, design a peer to peer search engineer system which depend on super node, finally implement the search arithmetic.Give out a peer to peer system structure, a complex peer to peer system structure; by synthesize Decentralized Unstructured Topology Decentralized Structured Topology and Partially Decentralized Topology. Finally explain the method of design and realize this system structure, and give some improve advice.
