2020/11/26 Thursday
Today, I saw some introductions about advanced search on the Internet. After learning a bit, I want to make a summary so that I can check it when I need it.

1. Exact match ""

The double quotation mark is an exact match, and only the content that is exactly the same as the content in the double quotation mark will be searched.

2. Does not contain-

Sometimes some of the content we search will be related to popular vocabulary. At this time, we can use the minus sign-for
[要搜索的内容] -[不想包含的内容]
example, when we search for the king, we include a large amount of the glory of the king, we can use it.
王者 -荣耀
Note: the content to be searched must be between the minus sign There must be a space, and there must be no space between the minus sign and the content not included.
