You can use Startpage to get Google search results. It’s a meta search engine for Google, but it doesn’t expose any of your data. You can use it with DuckDuckGo’s Bangs feature. That way, DuckDuckGo can be your default search engine and you can make all of your normal search queries with DDG, but if you want to search on Google through Startpage, you just type !sp followed by your search query into DuckDuckGo and it will forward your search to Startpage. This also works with many many other sites, type !bangs into DDG to get the full list of supported websites.
