What needs to be done is to change which google search you use. Until recently, I used google.com/custom which is a stripped down google search. No suggestion box, no advertising and no maps etc. But sadly, that google search has recently been disabled by google and all your searches there now return a google "we're sorry" error page.
Here is a google search address without the silly suggestions. Just copy and paste it into your address bar, press enter and then make it your home page
That Google lettering in the above image, regularly changes (thank heavens).
