What problems are you running in to? I've been using duckduckgo at work for just over a year now (took a change of job as an ideal time to try a complete switch in search engine too), and it has been excellent. I've been getting almost as good results as I do from google on even from some fairly vague terms, and comparable to Google when I give it explicit text to search for. Unlike Google it also seems to pay a lot more attention to searching for what I'm asking for, instead of trying to play guessing games.

DDG does kinda suck at finding specific programming things sometimes. The results are just not as good for the more obscure and rare stuff.

This is because Google also tries to build a profile for you and serves different results based on that, while DDG will return the same thing for the same keywords to different people.

For searches in specific domains it is better to use bangs. For example prefixing with !py shows results from python manual.

I've found this to be true for Bing too. For general search, it matches Google in accuracy. But in the case when I want to find a specific compilation error, only Google gives me useful results. But I still use Bing, and switch to Google only for such stuff.
