Clear IE auto-complete box contents

After using IE for a period of time, the "Search" section of the website will leave the text you have entered. When you use it again next time, a drop-down box will appear, which is some words that have been searched before. How can I delete it? Usually we clear the "auto-complete" by right-clicking on the IE "Properties → Content → Auto-Complete", but this will clear all the "auto-complete" forms, and it is very inconvenient to use.

In fact, there is a very convenient and practical method: click the "search" blank bar, move the mouse to the searched word, press the Delete key when the blue color is displayed, you can clear that you do not want to stay Search term. This method is suitable for clearing all "forms" of a website.
