摘要
倒排文件作为现代大规模搜索引擎工作的一个核心技术,其原理简单,具备灵活高效的特点,具体体现在其根据需要可做到适当的变通。本文通过在给定搜索引擎系统内部参数的前提下对其吞吐率的研究,建立一种倒排文件性能模型,该模型有效地提高了倒排文件的运行效率。
Inverted file as a core technology of the modern large-scale search engine. The principle is simple, with a flexible and efficient features. Reflected in needed to do the appropriate modifications. This article by the premise of the internal parameters of a given search engine system throughput. Establishment of a performance model of the inverted file. The mod el can effectively improve the operating efficiency of the inverted file.
