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?

當您使用Google搜索某些內(nèi)容時，結(jié)果會以毫秒為單位返回，但是在您自己的硬盤上搜索文件可能需要幾分鐘。 是什么賦予了？ 為什么搜索引擎查詢比本地文件搜索更快？

Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites.

今天的“問答”環(huán)節(jié)由SuperUser提供，它是Stack Exchange的一個分支，該社區(qū)是由社區(qū)驅(qū)動的Q＆A網(wǎng)站分組。

問題 (The Question)

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

超級用戶閱讀器Arne想知道為什么他的本地搜索與搜索引擎查詢相比如此之慢：

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

當我在Windows 7或Windows XP中的HD上搜索文件時，需要幾分鐘才能完成該過程。

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中填寫搜索字詞，則答案會以毫秒為單位顯示在屏幕上。 Google如何搜索比我的硬盤大許多倍，比操作系統(tǒng)搜索我的計算機快的Internet。

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

它僅是計算能力和正確算法的問題嗎？

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.

當然，他并不是唯一注意到這一差異的人。 開箱即用，沒有基于定制操作系統(tǒng)的搜索，這真是太慢了。

答案 (The Answers)

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

超級用戶貢獻者Simon強調(diào)了Google搜索查詢和非索引Windows搜索之間的根本區(qū)別：

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不在搜索互聯(lián)網(wǎng)：它正在搜索索引。 Google有龐大的服務器場，這些服務器場正在不斷掃描和索引互聯(lián)網(wǎng)。 該過程需要很多時間，就像搜索未索引的硬盤驅(qū)動器一樣。 在Windows 7中，有一個索引硬盤的選項。 這個過程最初需要一些時間，但是一旦啟動并運行，搜索結(jié)果將立即生效。
