This was my experience with DDG as well. For everyday searches, it does a fine search. But it fails pretty miserably with complex technical queries which is probably 95% of what I use web search for. For that reason, after trying DDG for about a year (for the second time) I switched to startpage.com.
Thx for the info on startpage.com. Never heard of it till this thread on HN. Just made it my homepage and added it to my tool bar.
I switched to DDG a couple years ago after becoming concerned about privacy. Unfortunately, DDG has never quite cut it for me in terms of search results. I do a TON of technology related searches, particularly wrt very obscure programming related technologies, especially related to embedded target dev. DDG always comes up short, and I typically end up doing "!g" searches. So startpage.com appears to the best blend of privacy + good search results. For me anyway...
