I believe everyone uses search engines frequently, but sometimes when you want to search for a certain piece of information, you find a lot of irrelevant ones (Baidu: What are you looking at me for?).Below we will introduce several search techniques that can improve search efficiency and help you quickly look up information.

Tip 1: Eliminate distractions

way : Keyword 1+space+minus sign+keyword 2, that is 关键词1 -关键词2

Function: Exclude some unwanted keywords

Example:

锤子 -锤子手机

An example of excluding search results with 锤子手机 Related, show only 锤子 The way it is.

After testing on Baidu search, some keywords can be excluded, but some are not easy to use.

Tip 2: Precise search

way : Add double quotes to keywords, "关键词"

Function: Only search for words in quotation marks, even if one word is missing or the word is split, it will not work

Example:

"达拉不崩吧"

Note the double quotes in English

Tip 3: Search within a specified website

way ： site:域名 关键词

Function: Search only the content of the specified domain name

Example:

site:zhihu.com 前端

Some of the built-in searches on some sites are not easy to use. You can try this search technique.

Tip 4: Specify the file format

way ： filetype:文件格式 关键词

Example:

filetype:avi 你懂的

Common file formats include doc, pdf, ppt, etc.

Tip 5: Specify search in title

way ： intitle:关键词

Function: The searched keywords must appear in the title

Tip 6: Specify search within content

way ： intext:关键词 、 allintext:关键词1 关键词2 、 inurl:关键词2

Tip 7: Use multiple search techniques together

Example:

site:zhihu.com 前端 intitle:js

Use multiple techniques and keywords in a superimposed manner, separated by spaces.
