Syntax format:
Site: URL keyword
Or keyword site: URL
Note:
1. site: the colon followed by the site must be ":" In English, and the Chinese colon ":" is useless.
2. The url cannot contain http ://
3. The url cannot be followed by a slash "/", but cannot be followed by a slash/
4. Do not use www in URLs unless you have a special purpose,
Using www will lead to missing content on the website, because many website channels do not have www.
Other instructions:
1. Keywords can be found either before site: or after site:, the search results are the same.
However, no matter who you are, there must be a space between the keyword and "site.
2. For "site:" search, there can be multiple keywords, separated by spaces.
3. Supports mixing with other complex search syntaxes. Each syntax and keyword is empty.
4. In addition to websites, you can also search for website channels, but only those.
5. A website may have multiple languages,
