Using a search engine is the only way to find exactly what you are looking for among millions of websites. However, the disadvantage to using a search engine is that you may need to go extra lengths to protect your privacy, especially if you use a public computer. After performing a search, the words you type into the search box will auto-fill into the space when a similar search is typed. Luckily, it's possible to clear the history on a search engine. The method you use to cledo so depends on your Web browser.
Click the "Tools" menu at the top of the page and choose "Clear Recent History."
Click to open the drop-down box next to "Time range to clear." Choose "Everything."
Click to open the drop-down box next to "Details."

Select "Clear Now."
Click the "Safari" menu and choose "Preferences."
Select the "Autofill" tab.
Click the "Edit" button, which is next to "Other Forms."
Click on the search engine in the list you want to clear. For example, if you wanted to clear the Google search engine, click "Google.com."
Click "Remove" and select "Done."
Click the "Tools" menu at the top of the page and choose "Internet Options."
