Better Internet Searching: Using Search Operators in Google Search

The Google search bar allows us to include a number of search operators to make sure that the context of the search is better explained. 

This will help narrow down the results to (hopefully) more relevant results

Here is quite a comprehensive list of operators that can be used in Google search:

Reproducing what Google has to say:

Narrow down your search results by adding symbols and words to your search called search operators. Don’t worry about memorizing every operator - you can also use the Advanced Search page to create these searches.

When you search using an operator, don't add any spaces between the operator and your query. A search forsite:nytimes.com will work, but site: nytimes.com will not.

Search for an exact word or phrase  "search"	Use quotes to search for an exact word or set of words on a web page. This is helpful when searching for song lyrics or a line from a book. But only use this if you're looking for an exact word or phrase, otherwise you'll exclude many helpful results by mistake. "imagine all the people"
Exclude a word -search	Add a dash (-) before a word or site to exclude all results that include that word. This is especially useful for words with multiple meanings, like Jaguar the car brand and jaguar the animal.  jaguar speed -car pandas -site:wikipedia.org
Search within a site or domain site:	Get results only from certain sites or domains. For example, you can find all mentions of "olympics" on the NBC website, or any .gov websites.  olympics site:nbc.com  olympics site:.gov
Search for pages that link to a URL link:	Find pages that link to a certain page. For example, you can find all the pages that link to google.com. link:google.com
Search for pages that are similar to a URL related:	Find sites that are similar to a URL you already know. If you search for related sites to the Time.com, you'll find other news publication sites you may be interested in. related:time.com
Fill in the blank *	Add an asterisk within a search as a placeholder for any unknown or wildcard terms. Use with quotation marks to find variations of that exact phrase or to remember words in the middle of a phrase. "a * saved is a * earned"
Search for either word OR	If you want to search for pages that may have just one of several words, includeOR (capitalized) between the words. Without the OR, your results would typically show only pages that match both terms. world cup location 2014 OR 2018
Search for a number range ..	Separate numbers by two periods without spaces (..) to see results that contain numbers in a given range of things like dates, prices, and measurements. camera $50..$100
Find information about a site info:	Get information about a URL, including the cached version of the page, similar pages, and pages that link to the site.  info:google.com
See a cached version of a site cache:	See what a page looks like the last time Google crawled the site.  cache:washington.edu

Punctuation

When you search, most punctuation and special characters are ignored. However, there are some punctuation and symbolsthat work in searches.

Here are a few tutorials on how to mix and match options to search better:
