> That is also my experience with DuckDuckGo but all search engines. They ALL suck including Google Search. I don't know why, but the results are simply crap.

(obligatory disclaimer: I work for Google but not in Search, all opinions strictly my own, yadda yadda)

It's a scale problem. An (in my opinion) unsolveable one.

Google - let's say all search engine companies combined - employ N engineers working on search engines. They allocate those teams X dollars, and let's pretend that's all these companies do and their total income is Y dollars.

Around the world there are orders of magnitude more people - let's say 1000*N, I don't know if anyone has even tried to gather this data - trying to game the search results and get their thing to the top. Those people have a combined budget dramatically larger than X and (I suspect) significantly larger than Y. Oh, and the best of them are almost certainly sharing notes and tactics with each other.

Even if everyone working on a search engine is a 10X genius engineer, they're still at a multiple-orders-of-magnitude disadvantage.
