1.site----Specify the search scope in a specific site. But sometimes you need to find some special documents, especially for large websites. Proper use of site can help you get twice the result with half the effort.
For example: Cigarette website site:www.666yan.com
2 intitle----limit the search scope to the title. Generally speaking, the title is the outline of the entire article. Using this method can help you quickly find the article you need.
For example: cigarettes intitle:666 cigarettes
3 inurl----Some information of the url in the website address often has some meaning. You can find these links through inurl. For example, if you want to find technical documentation about photoshop, you can do this. You can find relevant knowledge in photoshop inurl:jishu.
4 Use double quotes or book title numbers for exact matching. This is mainly done to narrow the search scope.
For example: [China Cigarette Network]
5 Use the minus sign. As the name suggests, "-" is the content you do not want to query. This is mainly something that is relatively easy to confuse. For example, you want to watch a movie online but don’t want to download it. Because many webmasters like to put all playback and downloading in the page title. Then you can do it like this----[Horror Night at the Museum] intitle:Play online-Download
I wrote it down roughly, I hope it will be helpful to everyone.
It’s not easy to write an article late at night, so I left a link to my website. Show mercy.
