Track flight status

Enter the airline and flight number into the Google search box and get back the arrival and departure times right inside Google's search results.

Convert currency, metrics, bytes, and more

Google's powerful built-in converter calculator can help you out whether you're cooking dinner, traveling abroad, or building a PC. Find out how many teaspoons are in a quarter cup (quarter cup in teaspoons) or how many seconds there are in a year (seconds in a year) or how many euros there are to five dollars (5 USD in Euro). For the geekier set, bits in kilobytes (155473 bytes in kilobytes) and numbers in hex or binary (19 in binary) are also pretty useful.

Remove affiliate links from product searches

When you're sick of seeing duplicate product search results from the likes of eBay, Bizrate, Pricerunner, and Shopping.com, clear 'em out by stacking up the -site:ebay.com -site:bizrate.com -site:shopping.com operator. Alternately, check out Give Me Back My Google (original post), a service that does all that known reseller cleaning up for you when you search for products. Compare this GMBMG search for a Cruzer 1GB flash drive to the regular Google results.

Find related terms and documents

Ok, this one's direct from any straight-up advanced search operator cheat sheet, but it's still one of the lesser-used tricks in the book. Adding a tilde (~) to a search term will return related terms. For example, Googling ~nutrition returns results with the words nutrition, food, and health in them.

Find music and comic books

Using a combination of advanced search operators that specify music files available in an Apache directory listing, you can turn Google into your personal Napster. Go ahead, try this search for Nirvana tracks: -inurl:(htm|html|php) intitle:"index of" +"last modified" +"parent directory" +description +size +(wma|mp3) "Nirvana". (Sub out Nirvana for the band you're interested in; use this one in conjunction with number 7 to find new music, too.) The same type of search recipe can find comic books as well.

Make Google recognize faces

If you're doing an image search for Paris Hilton and don't want any of the French city, a special URL parameter in Google's Image search will do the trick. Add &imgtype=face to the end of your image search to just get images of faces, without any inanimate objects. Try it out with a search for rose (which returns many photos of flowers) versus rose with the face parameter.

ID people, objects, and foreign language words and phrases with Google Image Search

Google Image search results show you instead of tell you about a word. Don't know what jicama looks like? Not sure if the person named "Priti" who you're emailing with is a woman or a man? Spanish rusty and you forgot what "corazon" is? Pop your term into Google Image Search (or type image jicama into the regular search box) to see what your term's about.
