> DDG has little idea what you're looking for while Google links you directly to the docs of Elm's Dict data-structure.

You know you're looking for a data structure, right? Add structure to your query, and DDG will do fine. Easy fix.

The opposite case, when google thinks he knows what you're asking but it's wrong, is impossible to fix.

I don't want them to be smart, I want them to be predictable and search what I say, not trying to reinterpret the query.
