1. Parallel search
Search Content 1|Search Content 2
Use "A | B" when searching, that is, search for web pages that "either contain keyword A or contain keyword B".
2. Eliminate irrelevant searches
Search Content - Remove Content
That is, we exclude some unwanted keywords from the search results. The way to eliminate them is to add a "-" (minus sign) in front of the keywords we want to exclude
Note: There must be a space before the minus sign! There are spaces! There are spaces!
3. Specified website search
Search content site: baidu.com
Limiting the search scope to this site can improve query efficiency (similar to manually adding a site search function).
4. Search in the title
intitle: search content
The title of a web page is usually a summary of the content of the web page. If you limit the scope of the query content to the title of the web page, you will get a search result with a higher degree of matching with the entered keyword.
Note: There should be no spaces between "intitle:" and the following keywords!
5. Specify link search
Use "inurl:", and write the keywords that need to appear in the url before or after.
like:
python inurl:csdn
You can look up content about python. The "python" in the above query item can appear anywhere on the webpage, while inurl:csdn must appear in the webpage url
6. Accurate search
The keywords to be searched are enclosed with "xxx" (English double quotation marks)
7. Combination condition retrieval
If you want to retrieve two or more keywords, use (English plus sign) + to connect the keywords
