Go to https://startpage.com/
there you can add it as your home page, AND add it to your search list.
I don't think you will find a more secure search engine.
Read the disclaimer when you mouse over the 'Details' under the 'Enhanced by Google' crap.
YES it uses Google search, NO it doesn't cal home every time you use it.
Again, read the disclaimer.
EDIT> My settings for Search has only one search engine in it. Startpage!
