| 摘 要： | 在局部索引架构下,应用搜索引擎优化算法会对索引系统的性能带来负面的影响。目前主要有两种索引架构：全局索引和局部索引,本文针对它们各自的优缺点,应用搜索引擎优化策略,提出综合使用两种索引架构：索引系统整体上采用局部索引架构,并对高频关键词对的postinglist交集采用全局索引架构的方式,可以很好的解决这个问题。

| Abstract: | Using the optimizing algorithm of the search engine will bring negative effect to the index system in the part index-architecture. Focusing on the two main index-architecture currently and their advantages and disadvantages, a new method based on the optimized strategy was presented to solve this problem. In the method, part-index architecture is used for the main index system; meanwhile the full-index architecture is used for the intersection of the posting list. |
