Currently, it is very easy for websites to provide better search results (but still not good) compared to Google and other search engines like DDG due to the limited crawling, except perhaps for the top few 1000 websites with small enough number of pages/URLs so that at least Google can keep them fully indexed. This is also where dedicated "site search" providers can beat these search engines easily: they can offer a full crawl and depending on the size of the resulting index, they can bill the website owner (e.g. by storage used in GB or number of URLs).
