Or when I put an entire error message in quotes and it deems the number of results for that error message too low to be intentional so it deconstructs it into a useless mashy search of all the words in the error. Note, I don't mean when the results are zero, but even then I usually have to spend an annoying amount of time before I realize that my search actually had zero results instead of the millions it claims it had.
There was a time when google's cleverness was just enough to be useful, but it gets more and more clever (and frustrating) every year now.
The dynamic Google results page means that it's really difficult to refine a search based on the presently visible results which disappear as I update the search. I find that that behavior incredibly annoying, and greatly appreciate that DDG doesn't do this.
