Google search Tips

Punctuation and symbols

Even if you can use the following punctuation when searching, adding these punctuation will not necessarily improve your search results. If we don't think the punctuation will give you better results, you'll see suggested results for search terms that don't contain punctuation.

symbols	How to use
+	Search for a Google + page or blood type Example: +Chrome  orAB+
@	Find Social Tags Example:@agoogler
$	Find Prices Example:尼康 $400
#	Find popular # tags to search for hot topics Example:#throwbackthursday
-	Add a short cross before a word or site to exclude the site that contains the information in the search results. This method is especially useful when searching for words that have multiple meanings, such as "car brand Jaguar" and "Animal Jaguar". Example: jaguar speed -car orpandas -site:wikipedia.org
"	If you enclose a word or phrase in quotation marks, only the following pages will be displayed in the search results: the words in quotation marks and the same word order as in quotation marks. It is recommended that you use this search method only when you need to search for an exact word or phrase, or you may mistakenly exclude many useful search results. Example:"想象一下所有人"
*	Add an asterisk to represent any unknown or indeterminate word. Example:"省*就是赚*"
..	Use two full periods (without spaces) to separate two numbers to see search results within a specified number range. Example: Camera$50..$100

Search operators

Search operators are words that you can add to a search term to help narrow the scope of your search results. You don't have to worry about remembering every operator, because you can also use the Advanced search page to do this kind of search.

operator	How to use
site:	Get search results only from a specific site or domain. Examples: olympics site:nbc.com andolympics site:.gov
link:	Find a page that is linked to a specific page. Example: link:youtube.com
related:	Find sites that are similar to the URLs you've visited. Example:related:time.com
OR	Find pages that may use one of several search terms. Example:marathon OR race
info:	Get information about a URL, including the cached version of the page, similar pages, and pages that are linked to the site. Example:info:google.com
cache:	See how the page looks when Google last visited the site. Example:cache:washington.edu

Note : When searching using operators or punctuation marks, do not add spaces between the operator and the search term. For example, we can identify the symbol site:nytimes.com in, but not recognize it site: nytimes.com in the symbol.
