摘要

我们描述了一种新的多层搜索引擎架构。基于对查询日志分析的观察以及排序公式的属性，我们导出了一种在搜索引擎中对文档进行分级的方法。这可以提高性能，同时保持返回结果的顺序，从而保持相关性，几乎“不变”。该架构和方法已经在一个包含10亿个文档的电信级搜索引擎上进行了大规模测试。该架构极大地提高了容量，目前已被用于一个主要的搜索引擎。

Multi-tier architecture for Web search engines

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.
