This is severely hampered by the availability of Google. After a few false starts I ended up switching to DDG as my default search engine. My usage pattern is as follows: for things that are predictably easy to find (e.g. the queries "normal" people would issue), I use DDG. That's about 90-95% of all my queries. For obscure stuff, I add "!g" at the end of the query and go to Google. That's the remaining 5-10%, and I doubt anyone can do better than Google there. That way I get both the privacy and the long tail.
