With each new version, Microsoft added more "under-the-hood" functionality to Internet Explorer. So, even if you've been using this web browser for a while, here are powerful search tips you might not know about. First: how many times did you copy text, opened a Google tab (or other search engine), and pasted the text to search for it? No need to do that anymore: hit the Ctrl+Shift+L keyboard shortcut, or right-click and choose "Search using copied text"!
Talking about text you copy: how many times did you copy text to search for it? If the word or piece of text you want to search for is on a web page, you don't need to even copy it! As long as you've added at least one search provider to your web accelerators, you can right-click on selected text and choose "Search with Google" - for example. (How to change default search engine in IE.)
You probably already know that since Internet Explorer 9, the address bar and search box have been merged into a single text field. This means that you can perform web searches straight from the address bar! But if you've ever tried to search for a URL (internet address), you know that IE loaded the URL instead of searching for it. No problem: type a question mark (?) and a space before the URL! Hitting the Ctrl+E keyboard shortcut will automatically do that for you!
Bing (Microsoft's search engine) is automatically integrated into Internet Explorer, but you can add as many search providers as you like. The easiest approach is to download their spec file from the official "IE Gallery" website, hosted on Microsoft.com. Just select a search provider by clicking on their link, and click Add in the confirmation box that pops up, like on the screenshot.
Regardless of your default search provider, you can switch search engine on-the-fly from the address bar by clicking on its logo / button. Just typing the question mark will show all web accelerators you have installed that are filed as search engines. In the screenshot, even if Google is the default search (you can tell because it is highlighted), I can click on the Yahoo icon to use it for that particular search! Then, type your query and hit Enter to view the results.
