you imply that when someone that is not a programmer, and say works in the rare stones industry, goes to google to search for ruby gems, that they are not shown a bunch of programmer garbage?
So without thinking I type record plane 1939-1945 into Google. And guess what? I get information about hand planes, pictures of hand planes in the images section, links to ebay auctions for vintage planes etc, and in between these there were only a few results related to aircraft combat during WWII.
The same query in incognito mode doesn't return even a single link related to hand tools.
