Search operators: You can use search operators and other punctuation to get more specific search results. Except for the examples below, Google Search usually ignores punctuation.
Punctuation & symbols: Even though you can use the punctuation marks below when you search, including them doesn’t always improve the results. If we don't think the punctuation will give you better results, you'll see suggested results for that search without punctuation.
Symbol - How to use it
+ Search for Google+ pages or blood types. Examples: +Chrome or AB+
@ Find social tags, Example: @agoogler
$ Find prices. Example: nikon $400
# Find popular hashtags for trending topics. Example: #throwbackthursday
- When you use a dash before a word or site, it excludes sites with that info from your results. This is useful for words with multiple meanings, like Jaguar the car brand and jaguar the animal. Examples: jaguar speed -car or pandas -site:wikipedia.org
" When you put a word or phrase in quotes, the results will only include pages with the same words in the same order as the ones inside the quotes. Only use this if you're looking for an exact word or phrase, otherwise you'll exclude many helpful results by mistake. Example: "imagine all the people"
* Add an asterisk as a placeholder for any unknown or wildcard terms. Example: "a * saved is a * earned"
.. Separate numbers by two periods without spaces to see results that contain numbers in a range. Example: camera $50..$100
Search operators: Search operators are words that can be added to searches to help narrow down the results. Don’t worry about memorizing every operator, because you can also use the Advanced Search page to create these searches.
Operator - How to use it
site: Get results from certain sites or domains. Examples: olympics site:nbc.com and olympics site:.gov
link: Find pages that link to a certain page. Example: link:youtube.com
related: Find sites that are similar to a web address you already know. Example: related:time.com
OR Find pages that might use one of several words. Example: marathon OR race
info: Get information about a web address, including the cached version of the page, similar pages, and pages that link to the site. Example: info:google.com
cache: See what a page looks like the last time Google visited the site. Example: cache:washington.edu
Note: When you search using operators or punctuation marks, don't add any spaces between the operator and your search terms. A search for site:nytimes.com will work, but site: nytimes.com won't.
