| 摘 要： | 文章针对目前分布式缓存系统命中率低和查询处理时间长的问题，在分析某中文搜索引擎于2009年9月查询日志集的用户查询特征和热点内容分布特征的基础上，设计并实现了包括静态缓存和动态缓存的双级缓存结构。最后，从理论分析和实验数据两方面，论证了基于查询日志的双级缓存结构在性能方面更具优越性。

| Abstract: | Aiming at the problems of distributed caching system with low hit rate and long query processing time, user query features and hot content distribution about query log of the "Search Dog" in Chinese search engine in September 2009 are analyzed. Two-level cache structure including static cache and dynamic cache is designed and implemented. Finally, two-level cache structure based on query log with better performance is demonstrated from both theoretical analysis and experimental data. |
