As a search alternative I've really enjoyed using searx [ https://en.wikipedia.org/wiki/Searx ] instances for the past 6 months or so. Searx, like DDG, aggregates from search providers including Google, Bing, (Wikipedia, DDG, etc.)b ut you can customise it to control exactly which search providers it pulls from. And it has !shortcuts to quickly specify individual search providers, like !ddg for DDG. Source code available: https://github.com/asciimoo/searx
