Distributed search engine system productivity modeling and evaluation. Journal of Software, 2012,23 2 :253?265. Abstract : This study extends the current productivity models for a typical Web search engine system, which consists of a Web crawling system and an indexing system. Five different design schemata are characterized according to this model and are compared through power consumption, networking cost, system scale, and query efficiency. The half-WAN scheme, which consists of a WAN-based crawling system and a multi-cluster indexing system, is proved to be the best choice for a large-scale highly-efficient Web search engine. Key words: distributed search engine; productivity modeling; distributed crawling; distributed indexing; half- WAN-based search engine 摘 要: 针对分布式搜索引擎系统效能建模与评估问题,通过对当前分布式搜索引擎系统的建模与分类,扩展了 能耗与网络开销的成本模型;对 5 种构建搜索引擎系统的设计方案,从系统成本、系统规模和查询响应时间等角度 进行
