How to remove this history

I'm confused, the obvious answer is click remove or go on manage search history. But your previous posts make you out to be pretty smart, what gives? This a trick question?

Or do you mean the history of your posts on this site? They don't delete posts I'm afraid, PM a mod and ask if it is.

Obvious answer is as @Curious layman says, but are you logged in somewhere? Does the history come from brower or from somewhere else, such as a google account? 
 

Search net for "how to clear [name of browser that you are using] history".

e.g.

https://support.google.com/chrome/answer/95589

for Google Chrome.

for Microsoft Internet Explorer

TO CLEAR YOUR ENTIRE SEARCH BAR HISTORY:
-Open an Internet Explorer window and select the gear icon in the top   right-hand corner.
-Select Safety > Delete Browsing History.
-Select History, then select Delete.

Get CCleaner Free and clean out your IE/Edge  cache etc when you clean up whatever browser you are actually using as they pick up crap even if you never use those browsers.

I did a test to verify my idea above:

Search history in google while logged in on google account (used for gmail etc), plenty of entries:

Log out from google account (gmail) and clear browser history. There are no entries in search history:

Log in on google again, then there are entires again even if browser history was cleared (I have hidden the text due to privacy since the order of entries was not the same):

So I insist, check what online services that are in use and if any of them keeps history (like google above) so that it is not enough to clear the browser history.

In the case of google, check the history and history settings on myactivity.google.com/myactivity.
