Alamy maybe, but last time i looked IStock is not "godly" either.
try looking for "necktie" at Istock and see what you get. rabbis, business people, objects, ...
for the first few pages. no necktie as in isolated . not until quite a few pages.
OK I did, and the first five pages (I stopped after 5) were absolutely fine, every single images featured a necktie in the image somewhere, if however I had wanted an image of just a necktie I would have searched for 'necktie AND isolated AND single' which is how search engines are meant to work. Your example is not spamming, many people may want a photo of a businessman wearing a suit and necktie and as such these images are correctly keyworded. Using the word 'NOT' also works on many search engines for example 'businessman NOT necktie'.
"necktie nobody" does a nice job also.
Unlike many photos that don't have things shown, that are in the keywords, like interchange, traffic and highway, when it's a rural two lane country road in the photo, the simple necktie search has people wearing neckties.
Search engines do not interpret or read minds, they only do what we tell them to do. A one word, vague search for "necktie" only shows the the person doing the search needs to refine their query better. Which is a very polite way of not saying what I'm really thinking.
