DDG is my default search engine but there are some types of searches that it’s not good at yet, so I find myself often toggling between the two after I see that DDGs response isn’t going to cut it.

Earlier today I was searching for a really specific Python error message and google had zero results. I tried Yandex and got the correct result on the first response.

Each search engine seems to be optimizing for a certain type of query and answer.
