Fire The Field Of Search Engine System Design And Realization

This thesis describes how to develop a professional search engine system about the fire-fighting field. The system can be used in the routine monitor and management by the fire department of public security organ. The system can lighten the work load of the fire department and prompt the management's efficiency. At the same time, It can make the different fire department of the public security organ's work standardization and high efficiency.The thesis first introduces the environment of information building in the fire-fighting field, and analyzes the necessity to develop the fire-fighting information search engine system. Then the paper analyzes the demand owing to the fire-fighting special situation. The system is based on the Browser/Server architecture, taking the C#3.0 as the main developing language and the Microsoft SQL Server 2008 as the management database system. The search engine uses the Lucene.Net framework and some module such as data input subsystem, news search module, web capture module, web parse module, database import module, index module, search module to constitute the vertical search engine. The search engine supplies the information about the fire-fighting law, firefighting news to the client to search, query and analyze. Contrasting with other search engine, it is faster and more professional.The Search engine can run at the popular windows operating system and release as the internet information service. The system has powerful extensibility and convenient maintenance to run reliably and stably, and it supplies the much stronger security access control mechanism and much better convenience. At last, We conclude the method and technologies used in the system. We point out the direction and method about developing the more optimizing search engine and make it work with much higher performance.
