Until now, web history of what ever searches you have performed through Google, was separated from the other products of Google. This was done, in order to maintain and respect the privacy and sensitive nature of the items searched for.

In case you wish to safeguard your privacy and unable Google from combining the Web History with the information collected about you from other products, for instance YouTube or Google Plus etc, you must remove all the items listed in your web history. Further more, you would need to stop Web History from getting recorded anytime in futures.
