Can Baidu search with regular expressions?

Baidu's search engine can't recognize regular expressions. Regular expression, also known as regular expression and regular expression (English: regular expression, often abbreviated as regex, regexp or re in code), is a concept of computer science. Regular expressions use a single string to describe and match a series of strings that conform to specific grammatical rules. In many text editors, regular expressions are usually used to retrieve and replace text that conforms to a specific pattern.

Baidu search method is as follows:

(1) keyword search

Enter a keyword string in the search bar of Baidu homepage, and click the "Search" button. Baidu search engine will search Chinese classified items and website information in the database and news database, and display the search results after the search. Click the link to view the details.

(2) Use double quotation marks ("") for phrase retrieval.

Use double quotation marks to query websites that exactly match keyword strings. For example, if you enter "China Women's Football Team", you can find a website containing "China Women's Football Team", but you can't find a website containing "China Men's Football Team".

(3) Use "+"and "-"to limit the search.

When we need to retrieve two or more contents, we can connect several conditions with "+". The keyword string must appear in the results. For example, if you want to query Na Ying's song "Conquest", you can enter "Na Ying+Conquest".

When querying an account, you can use the "-"sign if you don't want to include another account in this account. For example, you want to find "fruit", but you don't want to include "apple". You can enter "Fruit-Apple". The function of minus sign is to make the search results reflect your needs, so that you don't have to worry about a lot of irrelevant search results.

(4) only search the website.

If you add "u:" before the keyword, the search engine will only query the URL. For example, enter "u: yahoo.com" in the search box on the webpage, and click the "Search" button, and all the URLs containing the character "yahoo.com" in the Uniform Resource Locator will be displayed.

(5) only search website titles

Add "t:" before keywords. Search engines only query website names. For example, enter "T: Network Technology" in the website search box, and click the "Search" button to display the website titles that meet the search conditions.
