Prerequisites for Internet users: online broadcast of search techniques

No matter whether you are a "Prawn" on the Internet or a "cainiao" on the Internet, when you are confused and wandering at the "Crossroads" on the Internet, there will always be a high "Roadmap" to direct you to your destination. This "Roadmap" is a search engine. It is with its help that our life will be so rich and colorful. To help your friends improve their search efficiency, I will summarize some frequently used search engine usage skills from this issue, hoping to help you.

Narrow Search Scope

To avoid the occurrence of another keyword when searching for a keyword, you can add the minus sign "-" (English minus sign) before the keyword and separate it with the Space key. For example, if you want to search for "" and do not see "", you can use the Keyword: "" (without quotation marks, the same below ).

Pinyin Chinese character conversion

Google uses the intelligent software system to automatically convert Chinese characters into pinyin keywords and provide corresponding prompts. When the input and actual pronunciation are inaccurate or incorrect, google provides fault tolerance and correction functions, and prompts users with the most appropriate Chinese keywords. For example, when you search for "Wan Luo Xing Wen", Google will prompt "are you looking for: wanluo Xingwen wanlu.com", where "Wang xinxin) "Wen" is automatically converted after the system has referenced possible pinyin errors.

Search for a specified domain

 

You can use "site: www.xxxxx.com" to search for a specific site. For example, if you search for the keyword "Nic" on the "China Computer Education News" website, enter "Nic site: www.cce.com.cn ".

Search for specific documents

Google currently supports 13 types of non-HTML file searches, including customized documents, Microsoft Office (.doc,.ppt,.xls,. rtf), Shockwave Flash (.swf), postscript (. ps), and other types of documents. The command is "keyword filetype: Document Type ". For example, if you want to find a. DOC file, enter "filetype: Doc ".

Search for webpages linked to an address

You can use "link: www.xxxxx.com" to search all web pages pointing to this URL. Note that you cannot use "link: Search" in combination with common keyword search. For example, we want to know how well-known the China Computer Education news website is on the Internet? Check how many web pages are linked to the website. Enter "link: www.cce.com.cn.
