1. Use the “site:” operator to limit searches to a particular site. For example, if I wanted to find posts on Now That's Nifty about cheese, I would type "cheese site:nowthatsnifty.blogspot.com."
2. Use Google as a spelling aid. Search any word, if it's spelled incorrectly, Google will suggest the correct spelling instead. Also, if you want to get a definition of a word, you can use the “define:” operator to return definitions from various dictionaries (for example, define: parasympathetic).
3. Use Google as a calculator. Google has a built-in calculator — try entering a calculation like 110 * (654/8 + 3).
4. Find out what time it is anywhere in the world. Just search for “time” and then the name of the city. For example, try: time Salt Lake City
5. Get quick currency conversions. Google can also do currency conversion, for example: 100 pounds in dollars.
6. Use the OR operator. This can be useful if you’re looking at researching a topic but you’re not sure which keywords will return the information you need. Example, dairy OR cows.
7. Exclude specific terms with the "–" operator. You can narrow your searches using this operator. For example, if you’re looking for information about American Idol but don’t want anything about Simon Cowell, you could try: “american idol” -cowell
8. Search for specific document types. Google can search the web for specific types of files using the “filetype:” operator. If you’re looking for a PDF file about cheese for example, you could try: cheese filetype:pdf
9. Search within numerical ranges using the ".." operator. Say, for example, you want to look for information about cheese relating to the 1950’s, you could use this search: cheese 1950..1960.
10. Area code lookup. Need to know where a phone number is located? Google will let you know where it is, and show you a map of the area, too. For example: 415
