I switched to DDG search three months ago, and unfortunately it's much inferior to Google. Maybe I've subconsciously optimized my queries for Google these past 20 years and need to rethink how to query using DDG, though.
The funniest one for me in google is +"foo" they decided people didn't actually mean it, so they changed it to +""foo"" - then when we all started doing that, they made the new secret "yes I really want that string" to be +"""foo"""
