Apple’s Shortcuts app is as powerful as you want to make it, and it can do some incredible things if you know how to wrangle it. You can also use it for some super simple things, like searching a website for text.
If you find yourself needing to search a website for something regularly, then you’re no doubt familiar with the site search operator. Head to Google—or use the address bar—and enter “site:nameofsite.com keywords” to search that site. Searching the How-To Geek website for Shortcuts, for example, would require “site:howtogeek.com shortcuts” and you’ll be rewarded with the results.
