Abstract:

The aim was to solve the problem, which the traditional search method couldn’t meet the searching demand in the National Agricultural Scientific Data Center. The original method of website search engine was summarized, and the open-source Lucene search engine’s principle and using method were studied. The means for building the full-text search engineer in the agricultural scientific data center was discussed. Three representative databases were also selected: the large one, the medium one and the small one, in the agricultural scientific data center and carried on comparative experiments for search efficiency with them. At last, these results were compared with those consequences from traditional search method. The experiments proved that: the search engineer based on Lucene had more efficient and the practical application should be satisfactory.
