Google Search - Search effectively

When it comes to the Google search box, you already know the tricks: finding exact phrases matches using quotes like "so say we all" or searching a single site using site:lifehacker.com gmail. But there are many more oblique, clever, and lesser-known search recipes and operators that work from that unassuming little input box. Dozens of Google search guides detail the tips you already know, but today I am skipping the obvious and highlighting my favorite obscure Google web search tricks.

Get the local time anywhere

What time is it in London right now? Ask Google. Enter simply what time is it to get the local time in big cities around the world, or add the locale at the end of your query, like what time is it hong kong to get the local time there.

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.

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:(htmhtmlphp) intitle:"index of" +"last modified" +"parent directory" +description +size +(wmamp3) "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.
