我们描述了一种新颖的多层架构的搜索引擎。基于查询日志分析的观察结果以及排序公式的属性,我们推导出一种在搜索引擎中对文档进行分层的方法。这样可以提高性能,同时保持返回结果的顺序,因此相关性几乎“不变”。该架构和方法已经在具有10亿个文档的电信级搜索引擎上进行了大规模测试。该架构提供了一个巨大的容量增加,并在今天使用的一个主要的搜索引擎。
We describe a novel multitier architecture far a search engine. Based on observations from query log analysis as well as properties of a ranking formula, we derive a method to tier documents in a search engine. This allows for increased performance while keeping the order of the results returned, and hence relevance, almost "untouched". The architecture and method have been tested large scale on a carrier-class search engine with 1 billion documents. The architecture gives a huge increase in capacity, and is today in use for a major search engine.
