If you would like to see a history of the pages you've visited, choose "Your data in Search" in the Settings Menu. This will bring you to your "Search History" Page in Google. You (and Google) are the only ones who can view this page. It's useful for finding sites you've visited but can't remember.

You can exclude a word from your search by putting a minus sign ("-") immediately in front of the term you want to exclude. Make sure you include a space before the minus sign.

Google indicates that a common word has been excluded by displaying details on the results page. If a common word is essential to getting the results you want, you can include it by putting a plus ("+") sign in front of it. Include a space before the "+" sign, but not after it.
