I'm rather shocked how the quality of their search results has tanked over the years. I used to be able to find decent academic content, or programming related topics quite consistently 5 years ago. Now I'm getting only a few vague results either from stackoverflow, math stackexchange, reddit, or apple, and the rest is just utter garbage. Yandex, of all search engines provide consistently better results. Fortunately, Google Scholar did not suffer this fate yet, but I'm dreading the day when it will.
