When you search for something using Google, the results are returned in milliseconds, but searching for a file on your own hard drive can take minutes. What gives? Why is a search engine query faster than a local file search?

当您使用Google搜索某些内容时，结果会以毫秒为单位返回，但是在您自己的硬盘上搜索文件可能需要几分钟。是什么赋予了？为什么搜索引擎查询比本地文件搜索更快？

问题 (The Question)

SuperUser reader Arne wants to know why his local search is so slow compared to a search engine query:

超级用户阅读器Arne想知道为什么他的本地搜索与搜索引擎查询相比如此之慢：

When I search a file on my HD in Windows 7 or Windows XP it takes some minutes to finish the process.

当我在Windows 7或Windows XP中的HD上搜索文件时，需要几分钟才能完成该过程。

If I fill in a search term in Google, the answer is on my screen in milliseconds. How is it possible for Google to search the Internet, that is many times larger than my hard drive, faster than my OS can search my computer.

如果我在Google中填写搜索字词，则答案会以毫秒为单位显示在屏幕上。 Google如何搜索比我的硬盘大许多倍，比操作系统搜索我的计算机快的Internet。

Is it ‘only’ a matter of computing power and the right algorithm?

它仅是计算能力和正确算法的问题吗？

He’s certainly not the only one who has noticed the discrepancy; right out of the box with no customization operating-system based search is pretty darn slow.

当然，他并不是唯一注意到这一差异的人。开箱即用，没有基于定制操作系统的搜索，这真是太慢了。

答案 (The Answers)

SuperUser contributor Simon highlights the fundamental difference between a Google search query and a non-indexed Windows search:

超级用户贡献者Simon强调了Google搜索查询和非索引Windows搜索之间的根本区别：

Google is not searching the internet: it is searching an index. Google has huge server farms which are constantly scanning and indexing the internet. This process takes a lot of time, just like the search of your unindexed hard drive. In Windows 7, there is an option to index your hard drives. This process takes some time at first but once it is up and running the results of a search will be instantaneous.

Google不在搜索互联网：它正在搜索索引。 Google有庞大的服务器场，这些服务器场正在不断扫描和索引互联网。该过程需要很多时间，就像搜索未索引的硬盘驱动器一样。在Windows 7中，有一个索引硬盘的选项。这个过程最初需要一些时间，但是一旦启动并运行，搜索结果将立即生效。
