Design And Development Lucene.NET Lan-based Full-text Search Engine

The 21 st century is the era of information explosion, the rapid development of Internet technology, making a lot of information in our lives in this world. Faced with massive information, seek a scientific, rational search mechanisms become the most important task. Search engine is in this backdrop made. It means a certain strategy, the use of specific computer program to gather information from the Internet, the information is organized and processed to provide users with search services, users retrieve the relevant information presented to the user of the system[1].Full-text search engine is the most widely used major search engines, it is represented by Baidu and Google and other major search engines, they have been very successfully used in all aspects of people’s lives. However, information on the current utilization of the network point of view, is still very low. People in massive data information is still not well positioned to meet diverse needs. This article from another perspective another way, a small amount of data from the start, the depth of the potential value of data mining. We will limit the scope of the network reptiles in the LAN, using the open source Lucene full-text search tool kit, developed within a LAN-based station search engines. It is full-text search engine and mainstream similar, with the search and process information, and the results retrieved presented to the user’s basic functions. Its innovative two points, first, be able to crawl inside the station depth data LAN-based network reptiles, and have real-time high. Second, the system shields the station outside information that will limit the scope of the search in a specific local area network, to better meet the needs of the station personnel search. This search engine is suitable for a number of universities, small and medium enterprises or research institutions and other units.This paper introduces the research status of search engine technology, as well as research value and significance. Then the search engine technology for the research process several key technologies are introduced one by one. For example: web crawler technology, full-text search technology, Chinese word segmentation technology. Then focus on the open source Lucene search tools package. Then according to the method of software engineering, the project needs analysis, system design, module implementation. Finally, to complete the test system.Finally, the search engine technology to conduct research summary and outlook.
