Abstract


As we all know , the Internet has grown in strength as it has become the largest repository of information . Faced with such a huge Internet resource , from which the user how fast , accurate and comprehensive access to the required information has become an urgent problem . To help users solve this problem , there has been search engine. In recent years , as China's online recruitment market continues to expand , the majority of job seekers had to spend a lot of time in a tedious job sites on the registration and find jobs , and even become a special period of full-time work . A new network tool - job search engine launched quietly started to make this situation change . Search' dissertation">Job Search Engines are a vertical search engine , which can handle a large number of job recruitment site , recruitment information for job seekers to provide accurate and efficient search service. This paper introduces the concept of vertical search engines and the difference between traditional search engines , introduced the system architecture and the Lucene index structure . Analysis of the main vertical search engine technology , to discuss the implementation of the Lucene text retrieval process and the practical application of Lucene . This paper analyzed the vertical search engine for job seekers principles of technology and its implementation process, recruitment site for the use of the famous collector for information extraction and use Lucene indexing on the extracted information in order to construct a job -oriented vertical search engines. The system uses the open-source toolkit Lucene implementation program functions , the overall system is divided into the thesaurus module, database module, an information collection module , indexing and retrieval module module . Based on job seekers search for information on the actual requirements, analysis , design and implementation of the system , mainly to improve the system retrieval speed and retrieval accuracy for system design.
