The Research On Key Technology Of FTP Search Engine

With the improvement of network bandwidth,the Internet files stored on the numerous, some of which are stored in the FTP server. Simple FTP protocol FTP search engine that can greatly enhance the FTP file search speed accuracy and enhance the search efficiency.This article analyzes in detail the working mechanism related FTP protocol to study the working mechanism of FTP search engines,FTP search engine analyzes the status of research progress,set goals and expectations of the content. Of the FTP search engine performance. According to the system design requirements,design a Web-based interface,provide flexible query. The system consists of four modules,the basic system data, input and output interface,the string matching algorithm,the central query server, and the design of the various modules illustrated introduction. Then,given the system design and implementation details of each module in the data structure and implementation of the file attribute to filter search results and other functions,which are rich in the search engine function to a certain extent,improve the retrieval accuracy and precision, to out of Prospect search engine performance. Finally,he prospect of research are analyzed,pointing out that the search engines need to improve several major issues,such as file too large,the data need to close the search engine updates,system requirements and other issues large consumption.
