If you know the exact address (URL) of a website, you can type it in your browser's address box and go directly to it. Most of the time, though, you will use a search engine to find information on the web. Unless the search engine gets good directions from you, you may become lost in a sea of misinformation, advertisements, and opinions. With a little practice, you can make sure your search engine stays on track, arrives at its destination, and delivers good results.
No search engine indexes all of the web, and while quite a bit of the content found by the various search engines will overlap, much of it won't. In other words, different search engines will give you different results. You may need to try more than one to find what you need.
Below are a few of the many search engines available. Many other search engines have come and gone or been acquired by other search engines. The "big three" general search engines are Google, Yahoo, and Bing but there are many smaller ones, including private ones and specialized ones. Besides the "big three" you might enjoy using the lesser known Gigablast or DuckDuckGo!
