If the query returned 0 results and didn't have any syntax (no intitle:foo) in it, should we try _harder_ to get suggestions? I don't know exactly what that changes that means but we can totally implement the retry if we think it'll help.

The idea is that it might not be performant enough to run super duper strong suggester settings all the time and when there are no results it important to have suggestions.

For reference, only 20% of 0 results queries that I counted this morning returned a suggestion. I don't know how many asked for it though.
