Search operators supported by Google.

• "exact phrase": Double quotes indicate that you are looking for pages with the exact word or phrase. For example, one might search for "passive reconnaissance" to get pages with this exact phrase.
• site:: This operator lets you specify the domain name to which you want to limit your search. For example, we can search for success stories on TryHackMe using site:tryhackme.com success stories.
• -: The minus sign allows you to omit search results that contain a particular word or phrase. For example, you might be interested in learning about the pyramids, but you don’t want to view tourism websites; one approach is to search for pyramids -tourism or -tourism pyramids.
• filetype:: This search operator is indispensable for finding files instead of web pages. Some of the file types you can search for using Google are Portable Document Format (PDF), Microsoft Word Document (DOC), Microsoft Excel Siadsheet (XLS), and Microsoft PowerPoint Presentation (PPT). For example, to find cyber security presentations, try searching for filetype:ppt cyber security.
