Google Search Doesn't Want You to Find Anything, It Wants You to Keep Looking Forever

Google Search is so inefficient it defeats its own stated purpose.

Or maybe it's not inefficient at all, I am now positive its real purpose is not to let you find something on the Internet but rather to keep you looking as long as possible, preferably for ever.

For example, I was looking for men's black leather blazers specifically (as in suit jacket but NOT other types of jackets) but it keeps turning up anything but what I am looking for -- all sorts of jackets but very few blazers or costume looking jackets.

When I specify "leather BLAZER", the dumb thing still returns mainly "leather jackets".
