Go to demos of the various keyboards from the manufacturers and dealers and make a note of the demonstrators name, (As in most cases these are also the style creators) then do a search for them, obviously if it is in a print magazine then you will need to contact the magazine direct to purchase the relevant copy.
For Korg & Yamaha Owners also have a look at this site

Unless you are using a so called security browser/search engine (If so just use Chrome, Firefox or Edge and Google or Bing as your search engine) I cannot see why you are having problems finding the results you require unless your country is blocking sites it deems unsuitable for you, in which case you will need to use a VPN.
