Re: It's useful. (Unlike most must-have tech)
Well, you should be able to ask any search engine for exact search terms and exclusions and actually get a result on that basis.
Instead you get curated results that would rather sell you a holiday in Devon (or a holiday home!) than give you the information you are seeking.
Search machines - with CGPT or not - are sometimes (often) useful, but they do not have your interests at heart. Not if there's something that can be sold to you.
