While I see this is for their Workspace offering. If there is anyone who is discussing about Google search and DuckDuckGo, DDG has been competent enough (subjective) for a long time. And any incompetence of search can be worked around using DDG !bangs for those who are not aware of it - http://duckduckgo.com/bangs.

Bangs essentially lets you search directly on websites like Stack Overflow, Wikipedia, Amazon, Mozilla Developer Network, Arch Wiki and many many websites. Its a really great productivity hack.
