An Algorithm for Ranking Pages Based on Theme Seach Engines

With the development of information technology, it is very difficult for users to find the information they need because more and more information is on the Internet. The search engine is a tool for users to find information, however, customers are not satisfied with the results which search engine returns. This paper first introduces the sorting algorithm of Lucene, and then it represents the PageRank algorithm of Google and analyzes the algorithm deficiencies. In order to improve the PageRank algorithm, this paper comes up with time feedback factor. In addition, the paper puts forward a integrated sorting algorithm with Lucece, PageRank, user feedback and response time as the sorting factor of the algorithm, so as to overcome the Shortcoming of single sorting algorithm. Finally, on the basis of the Lucene, this paper designs and implements an agricultural theme search engine. The experiments have shown that the algorithm is able to meet the users´ requires.
