You need to insert the Parameter:
psw=0on your Google Query URL.
So if in your Browser bar the Google URL look like "http://www.google.com/" you need to:
- Add "?psw=0" to the URL -> http://www.google.com/?psw=0
- Reload your Page
- Make your Depersonalized Search
The "?" come from the following Google Query Parameters Syntax:
- The First Google Parameter Must be Preceded by a "?"
- The Following ones, I mean the second... Must be Preceded by a "&"
So for a Depersonalized Search without Auto-complete your URL Address shoud look something like: http://www.google.com/?autocomplete=0&psw=0
If you Need to Perform Often this kind of Depersonalized Searching it's Best to make a Bookmark
