Google has updated its search results and will display search results for punctuation marks and other symbols. Search symbols include commas, question marks, periods, percent signs, and so on, and these results will be returned in the search results, although they are not always very relevant, as shown in the following figure.
The search results of the punctuation mark change the results of the search, which can be searched to the results of the punctuation include:
。 Period
, (comma)
: (colon)
;(semicolon)
# (digital symbol)
% (Percent semicolon)
@ (at symbol)
^ (caret)
() {} [] (parentheses, brackets, and braces are all grouped together into the same search results)
~ (wave number)
Vertical
"(quotation marks)
< (less than number)
> (greater than Number)
$ (dollar sign)
Other symbols and punctuation, Google can identify and return results:
! (exclamation number)
' (apostrophe)
& (and number)
_ (Underline)
-(minus sign)
+ (plus)
= (equal sign)
\ (back slash)
/(Slash)
There is still a symbol that cannot return the result, which is an asterisk (*), as shown in the following figure
In other search engines, including Baidu, Yahoo, Bing and other search engines, these symbols can not return the search results. Google is the current search engine leader, I believe that other search engines will follow this search function.
