Useless search engines from Google and the like.
I know that this is not a mainstream case and slightly off-topic but I have found the big search engines to be useless unless you want to buy something from the larger multinationals.
It may have improved by now but a few years ago if I put something like ''Ulnar fracture'' into a search box the first page would be filled with things like ''get your next ulnar fracture from amazon'' or similar. Fucking useless for anything except the promotion of amazon..
Same if I wanted to find details on something just as specific related to my work. I may be looking for Radon Gas barriers but the top listings would be companies selling gas and electricity and wanting you to switch providers. Keywords or whatever may serve a purpose but not in most cases where ''gas'' doesn't automatically mean you want to change your gas provider.
Very similar is the propensity for any English search term to throw up loads of US sites regardless of what you put in as a search term or tried to restrict to UK English. If the searches are no good then no point trying to use them.
I use DDG when I have to or try to find details by other means but for me the search engine has been nothing but a waste of time and maybe things like this will change them for the better. ( It's Friday so I am allowed a bit of optimism...)
