Baidu and Google's most comprehensive search engine advanced grammar collection and its usage

Want to learn SEO, then we first from the most basic search engine syntax, the following collation Baidu, Yahoo, Google search for the three major high-level grammar and application.

Baidu Search Advanced Grammar
1. Limit the search scope to the title of the page--intitle
Page headings are usually sketchy to the content of a Web page. Limit the scope of the query to the title of the page, sometimes to achieve good results. The way to use it is to put the contents of the query, particularly critical parts, with the "intitle:" Collar up. such as: SEO intitle: Dance of the Spirit
2. Limit the search scope to a specific site--site
Sometimes, if you know what you need to find in a site, you can limit your search to this site and improve query efficiency. The way to use it is after the contents of the query, plus "site: Website domain name."
For example, SEO site:www.hnfree.cn
3. Limit the search scope to the URL link--inurl
Some of the information in the URL of a Web page often has some valuable meaning. As a result, you can get a good result if you make a certain limit to the URL of the search results. The way to do this is to use "inurl:" followed by keywords that need to appear in the URL. such as: SEO service Inurl:hnfree
4. Exact match-double quotation mark and title number
If the input query word is very long, Baidu after analysis, given the search results in the query words, may be split. If you are not satisfied with this situation, you can try to let Baidu do not split the query word. This effect can be achieved by adding double quotation marks to the query words. such as: "Fury seo Service"
5. Requires no specific query words in search results
If you find that there are certain categories of pages that you do not want to see in your search results, and that these pages contain specific keywords, you can remove all pages that contain specific keywords by using the minus syntax. such as: SEO Services-Fury

Google App guide: Advanced search Syntax
1, "site" means that search results are limited to a specific website or website channels, such as "www.hnfree.cn", "edu.sina.com.cn", or a domain name, such as "com.cn", "com" and so on. If you want to exclude a site or a domain-wide page, simply use the "-site/Domain name". such as: SEO site:www.hnfree.cn
2. The "link" syntax returns all pages linked to a URL address.
Example: Search all pages with links to "www.guanyufanyi.com" to the translation company. Search: "Link:www.guanyufanyi.com"
3. The "inurl" syntax returns a page link that contains the first keyword, followed by a keyword that appears in a link or in a Web page document. There are a number of sites that have the same properties of a resource name displayed in the directory name or page name, such as "MP3", "gallary", and so on, you can use the Inurl syntax to find links to these related resources, and then, with the second keyword to determine whether there is a specific information. The biggest difference between inurl syntax and basic search syntax is that the former usually provides very accurate thematic information. such as: Search: "Inurl:pdf seo"
4. The "Allinurl" syntax returns a link to the Web page that contains all the query keywords. The object of this query is focused only on the link string of the Web page.
Example: Find a company web site that may have a PHF security vulnerability. Usually the Cgi-bin directory of these Web sites contains the PHF script (which is unsafe) and is represented in the link as "Domain name/CGI-BIN/PHF". Syntax: "Allinurl:" Cgi-bin "PHF +com"
relatedA similar web page used to search for structural content. Example: Search all the Chinese Sina homepage Similar pages (such as NetEase home page, Sohu Home, China net home, etc.), "related:www.sina.com.cn/index.shtml".
CacheUsed to search the cache of a page on a Google server, which is the same feature as a "Web snapshot", typically used to find some dead linked pages that have been deleted, equivalent to using the "page snapshot" feature in the normal search results page.
InfoUsed to display a series of searches related to a link, providing the ability to cache, link, related, and pages that fully contain the link.

Yahoo Advanced Search Syntax
"Title:" is used to search for the title. For example: Search the title: Jacky, the search engine will return all the headings contain "Jacky" page. Because the title of the page usually describes the content of the page accurately, it may be more accurate to search with "title:".
"Link:" is used to find all pages linked to a URL. For example: Search link:http://www.yahoo.com.cn/, will get all links to "www.yahoo.com.cn" page; search Yao Ming link:http://www.yahoo.com.cn/or Link:http ://www.yahoo.com.cn/Yao will get all the pages that link to "www.yahoo.com.cn", including the word "Yao". Please note: "/http" must not be missing when searching.
"Site:" or "domain:" is used to limit the source of search results. For example: Search
Yao Ming site:yahoo.com.cn or Yao Ming domain:yahoo.com.cn or the "Yao" and site, domain statement Exchange location (note the middle of using spaces separated), the search engine will return in the domain name "www.yahoo.com.cn" And its subdomains, all pages that contain the word "Yao".
The usage of "hostname:" is the same as "site:", "Domain:", except that when you use "hostname:", only the pages that are under the current domain name are returned, not the pages in their subdomains.
