Google Search Operators (GSO)
Google Search Operators (GSO)
Below is a list of search operators to assist in the research process
Place quotes around a "search term or phrase" which will force an exact-match search. Use this to refine results for ambiguous searches, or to exclude synonyms when searching for single words. Example: "Steve Jobs"
Use the minus sign (-) to exclude a search term or phrase. In our example, any pages returned will be related to jobs but not Apple (the company).
Example: jobs -apple
Use filetype to restrict results to those of a certain filetype: PDF, DOCX, TXT, PPT, etc..
Example: apple filetype:pdf
Use site to limit results to those from a specific website.
Example: site:apple.com
Use related to find sites related to a given domain.
Example: related:apple.com
Use intitle: to find pages with a certain word (or words) in the title. In the example, any results containing the word “apple” in the title tag will be returned.
Example: intitle:apple
Use allintitle: which is similar to “intitle,” but only results containing all of the specified words in the title tag will be returned.
Example: allintitle:apple iphone
Use inurl: to find pages with a certain word (or words) in the URL. For this example, any results containing the word “apple” in the URL will be returned.
Example: inurl:apple
Use allinurl: which is similar to “inurl,” but only results containing all of the specified words in the URL will be returned.
Example: allinurl:apple iphone
Use intext: to find pages containing a certain word (or words) somewhere in the content. For this example, any results containing the word “apple” in the page content will be returned.
Example: intext:apple
