TLD-Specific Searches
Many website addresses end in .com, which is the most familiar of the top-level domains (TDLs). However, it isn’t alone. Other top-level domains that use other suffixes exist. Some of the most common of these include:
.net (an alternative to .com).org (typically for but not restricted to nonprofit organizations).gov (for government sites).edu (for educational institutions).mil (for military use).uk, .us, .au and others (country-specific domains)
To search a specific top-level domain, simply precede it with site: followed immediately by the TLD suffix without a space between them. Then, add a space and type the term for your search. For example, say you’re looking for information about textbooks, but you don’t want to buy a textbook. An internet-wide search would show you mostly websites that sell textbooks. To get noncommercial search results about educational textbooks instead, confine your search to the .edu top-level domain, by typing this into the search field:
You can use this method to restrict searches to any TLD.
Domain-Specific Searches
Taking this trick a step further, you can also search within any second or third-level domain. For example, if you’d like to see what Lifewire.com has on the topic of routers, you type the following into the search bar: The search results focus on articles about routers on Lifewire, not on other sites. Domain-specific searches can use other Google methods to tailor your searches, such as boolean searches and wildcard searches.) One of the most basic is to add quotation marks around a group of words to indicate you are searching for a phrase. For example: In this case, the quotation marks tell Google to use its contents as a search phrase, rather than as separate words. You won’t get results that have artificial but not intelligence. You’ll receive search results from Lifewire.com on the phrase artificial intelligence.
