Research On Search Engine For The Coal Subject

As the Internet information has increased dramatically,and the diversified information has formed,traditional inductive type of search engine including collection,index and search content has been expanding constantly.The demand for efficiency and diversification of users has also becoming increasingly unsatisfactory.In particular,it cannot satisfy the particular users' needs for the formation of restricted category and oriented to specific topics.As a result,policymakers in the coal enterprises have carried out a major strategic plan to improve the traditional coal industries by informatization.Many domestic coal,mining research institutes,universities,government departments and enterprises are establishing the coal information website based on its own data.This article aims to structure a model of coal-oriented search engine by analyzing the research status of Cloud Computing and the search engine technology at home and abroad,combining the coal industry research status.This paper first introduces the Cloud Computing Technology and the involved key technologies to build a search engine.The main technical support in this study is confirmed by comparison.Then coal topic search engine oriented market demand,system architecture is analyzed,and the technical difficulties of system construction are found.Therefore,a set of effective methods is summarized,laying a solid foundation for the construction of search platform.Finally the search engine completes the implementation and testing based on the preliminary planning.This search engine has collected a large amount of information in this field,so it can provide users who are interested in coal with timely and concentrated information,avoiding a large number of invalid information in the process of searching.Hence,it can optimize the search efficiency and offer users a platform on which they can communicate with each other,share information and resources,as well as forecast industry development trend.The results of the study show that the coal theme oriented search engine has certain universality.The engine can be applied to other industries in the future,using high-technology to serve the society,further improving the economic and social benefits.
