There is only one search engine that I use and that is google. Not only do I like the clutter-free, minimalist design of the webpage, I when I search something on the web is always come up with more options than my the search engine of yahoo or msn. There is all the more reason to love google, unless of course, you already know the following tricks:
10. Get Local time. Type what time is it, followed by any city to get the current time.
9. Track Flight Status. Enter the airline and flight number to find out the departure time and estimated time for arrival for any flight.
8. Convert Currency, Metrics, Bytes and More. Google has a built-in converter calculator. You enter quarter cup in teaspoons, seconds in a year, US dollars in Euros, and countless others.
7. Search for pages that are "Better than," "Similar to," or "Reminds me of:" Enter Better than + keyword" or "similar to + keyword" to find webpages you never knew existed.
6. Use google as a free proxy. Enter Cache:website.com to view a website that's been blocked in your computer from using.
5. Remove Affiliated Links from Product Sources. To avoid seeing search results from certain sites: Enter site:website.com
4. Find Related Items: Enter ~ before any search term to find related items as well.
3. Find music and comic books. Enter -inurl:(htm\html\php) intitle: "index of" + "last modified" + "parent directory" + description + size (wma\mp3) "band or comic book name" to find music files and comic books
2. See Images of People, Objects etc.: Type in a search term, and click on images to see photo of the results.
1. Search for Faces. If you're looking for a a photo of a person named Rose and don't want to see photos of a flower, add &imgtype=face to the end of your image search. It will show you only images of faces.
