不会这些搜索引擎技巧，别告诉我你是搜索小能手（多图） - 搜素引擎,搜索技巧 - IT资讯
网络时代我们每个人都离不开搜索引擎。搜索引擎可以帮助使用者在Internet上找到特定的信息，但同时也会带给我们大量无关的信息，魏则西事件就是被搜索引擎广告推广所误导，最终酿成悲剧。那么如何找到我们想要的东西呢？其实我们在使用搜索引擎时，加上一些特定的关键字符，就会迅速找到我们想要的东西。
一般搜索
我们最常用的搜索方式就是这样，直接搜索关键字，笔者在搜索引擎中搜索“装机”关键字，推广页面就占了大半个屏幕。这种搜索方式优点就是简单方便，但是无关信息非常多，需要仔细甄别。
双引号搜索
在想要搜索的关键字加上双引号，加了双引号会进行关键字精确搜索，剔除读音相近的模拟算法搜索结果。
▲前几行的推广页面消失
括号搜索及加减号用法括号搜索
我们在使用搜索引擎时，例如搜索”使用电脑”，搜索引擎会将“使用”、“电脑”、“使用电脑”关键词结果显示出来，加上括号“（使用电脑）”，搜索引擎会把括号内默认为一个关键词。搜索结果如下：
▲不加括号
▲加括号
加号(+)减号(-)
在想要搜索的关键词前使用加号，也就等于告诉搜索引擎你搜索的这个词必须出现在搜索结果的网页中。例如搜索“电脑+攒机”，搜索引擎结果如下：
在想要搜索的关键词前使用减号，实质是与上面有些相反的意思，则在搜索结果中不能出现前面带减号的关键词。例如“电脑 -淘宝”（注意：减号前加空格，减号后面不需要空格）搜索结果如下：
▲搜索结果不含“淘宝”关键词
高级搜索技巧1限定字符搜索
有时候我们知道一篇文章的标题怎么搜索呢？这时候我们就要用到intitle语法了，在想要搜索标题关键词前加上intitle：，例如“intitle：装机不求人”显示出的搜索结果都是标题含”装机不求人“的内容。
限定域名搜索
把搜索范围限定在特定站点中，如site：某某.com。“site:”后面跟的站点域名，不要带“http://”；site:后面带不带www结果可能是不一样的，因为有些域名还包括二级域名，如：site:www.某某.com和site:某某.com,搜索结果就不一样；另外，site:和站点名之间，不要带空格。例如我想搜索中关村在线网站中有关DIY的内容，结果如下：
限定url搜索
inurl的作用是限定在url中搜索。任何网站的url都不是随意设置的，都经过一番过虑，有一定用意的。很多地方，url链接和网页的内容有着密切的相关。所以，可以利用这种相关性，来缩小范围，快速准确地找到所需信息。
网址url含有“mp3”，关键词“沧海”关键词结果
高级搜索技巧2link查询链接
link是SEO中比较常用的一个高级指令，主要搜索某个网站url的内部链接和外部链接，但这个指令并不是对每个搜索引擎都很准，并且是随机的一部分，而百度则不支持这个指令。使用雅虎搜索引擎搜索“link:zol.com”结果如下：
▲反向链接结果
博客限定搜索
使用blog：命令可以搜索所有博客中你所感兴趣的内容。
博客中含有“中关村”关键字搜索结果
网站外链数量查询
domain的作用是查询网站的外链，或者与网站有关联的外部链接。
限定文档类型搜索
最后一个可以说是最实用的功能，尤其是正在写毕业论文的同学一定要注意看。格式为：filetype:（文件件后缀名） 关键字。例如我们搜索“filetype:pdf 给水系统”显示内容如下。
搜索结果全是关键字为“给水系统”的PDF文档，很方便吧！
百度部分关键词彩蛋
除了这些小技巧之外，百度在搜索某些特定的关键词也会出现一些好玩的特效。
跳跃
黑洞
旋转
闪烁
抖动
是不是觉得特别有趣？想看百度搜索关键字彩蛋的同学一定要记得在PC端去试验！好了，关于搜索引擎小技巧就介绍到这里，大家使用搜索引擎时有什么心得也可以在文章下方留言。
