Search engines have been aiming for the lowest common denominator for a long time now. It's all about asking a vague question and letting it's knowledge of you and people like you lead you to the answer. I prefer telling it exactly what I want. Like every other piece of software these days, I keep fighting it because it tries to out-think me. Not a hard task some days, but still. Does DDG allow "and", "or", parens, etc? I tried a query of the form A and (B or C) and it brought back things but I can't tell if it just ignored the parens and "and" and "or" keywords or if it actually used them. Does it honor double-quotes and plus and minus signs? I tend to give DDG more information than it needs, such as "c programming enum" instead of just "enum" for example. I'd love to be able to treat it as a pseudo sql query instead.
