How Search Engines Operate
Search engines have a short list of critical operations that allows them to provide relevant web results when searchers use their system to find information.
Crawling the Web
Search engines run automated programs that use the hyperlink structure of the web to crawl the pages and documents that make up the World Wide Web. Estimates are that of the approximately 20 billion existing pages, search engines have crawled between 8 and 10 billion.
Indexing Documents
Once a page has been crawled, it's contents can be "indexed" - stored in a giant database of documents that makes up a search engine's "index". This index needs to be tightly managed, so that requests which must search and sort billions of documents can be completed in fractions of a second.
Processing Queries
When a request for information comes into the search engine (hundreds of millions do each day), the engine retrieves from its index a

怎么查寻引擎经营 查寻引擎有给他们提供相关的网结果重要操作的一个最后的名单当搜寻者使用他们的系统找到信息。 爬行网 查寻引擎奔跑自动化使用网超链接结构爬行页并且文件组成全世界Web. Estimates 是那大约20 十亿现有的页, 查寻引擎爬行了在8 和10 十亿之间的节目。 分度法文件 一旦页爬行了, 他的内容可能是"indexed" - 存放在组成一查寻engine's "index" 文件的一个巨型数据库; 。这个索引需要紧紧被处理, 以便必须搜寻的请求并且排序亿万文件可能被完成在一转眼工夫。 处理询问 当一要求信息进入搜索引擎(上百成千上万做□天), 引擎检索从它的索引匹配询问的所有文件。比赛是坚定的如果期限或词组被发现在页以方式由用户指定。例如, 一次查寻为 在Baidu 退回4,710 个结果, 但一次查寻同样词组在行情回归只2,410 个结果。在第一系统, 共同地叫做"Find all" 方式, Baidu 退回有期限" 的所有文件当在第二次查寻, 唯一那些页以确切的词组 返回了。其它先进的操作员(Google 有名单11) 能改变收效的搜索引擎将考虑一次比赛为一次指定的询问。 等第结果 一旦搜索引擎确定了哪个结果是一位对手对于询问, engine's 算法(一个数学等式常用为排序) 跑对每个的演算结果确定哪些与指定的询问是最相关的。他们排序这些在结果页在有条有理从最相关与最少以便用户能做出选择的选择。 虽然查寻engine's 操作不是特别长的, 系统象Baidu, Google, 雅虎! msn 居住并且soso 是在最复杂, 最处理密集的计算机之中在世界上, 处理成千上万演算□秒钟和集中对信息的需求对一个极大的小组用户。
