Here’s a little iOS 8 tip for quickly searching sites you’ve already visited in Safari: while in the address bar, start typing the first four or five letters of a website, add a space, and then type in a search term. You’ll find that the first result in the suggestion list (below the URL bar) will become an option to search that website, and tapping on that line will initiate the search.
The only catch is that you have to manually run a search on the website at least once (which is how Safari learns how the site formats search queries). In our example case, this means visiting www.iPadInsight.com, typing a search into our search bar, and then pressing enter to execute the search. Once you’ve done that once on our site, you’ll see results similar to the one in my screenshot above. This is a really useful feature for power users, since it saves you from having to load a website before actually getting to initiate your search.
This is also a great tip for people who want to keep the number of apps down on their iPads. You could download apps for Yelp and IMDB, but using this trick puts the powerful search results of those websites at your fingertips, without any extra apps to clutter up your home screen.
