When I know I'm asking an SO sort of question I can !so directly. The whole ! system transforms ease of use - I miss them elsewhere!

TL;DR I mostly find what I need quicker with least faffing around changing terms to try and fight them "knowing best".

Google shot themselves in the foot when they removed code search, and "improved" results by constantly knowing better with synonyms and other semantically linked results. It rather broke code searches and led to more of the wrong language turning up instead. Language reference and standard library type searches they do just fine at.

Google spoiled it for the obscure and code when even + and - modifiers and advanced searches became optional. They felt able to give a page of results with only one result having my must-have term. Makes searching for a specific release hellish - not everyone integrates latest and greatest v9 the week of its release. No, I really do want v7. I never fathomed the rationale of that change for anyone.

DDG do the least additional messing with my search terms with helpful expansion, pluralisation and so on. DDG got a little worse at obscure error searches when they started on some "oh you also meant" games fairly recently. They still do the least of this. There's still occasional cases where the content simply isn't there - but they're far better than say a year or two ago.

When I first tried DDG a few years ago I was !g or !sp all the time and it was barely worth the effort. Now I very rarely go near Google and don't feel I'm losing out.
