That's why I keep ddg.gg as my default search engine. Ctrl-K, and type:

!r "something"

!hn "something"

!so "something"

!ta "something"

And for some niche sites I submitted "bang" suggestions which were accepted.

Works great for technical search, e.g. !cppr for C++ reference.

In a rare case I need Google, I just add !g to my search.
