As Deskana originally said in T101774: I want us to figure out what users are searching for when they get zero results, so we can know whether they're actually searching for something that we can't give them meaningful results for (e.g. "isfnaifiabfiabuabig") or something where we could do better (e.g. "borick obama" which gives two mostly irrelevant results)
That task was narrowed to some easy/safe work. This remaining part is trickier, because search queries might contain private data. We can't just display them on a publicly-accessible dashboard. Maybe we can MD5 them, or maybe we can restrict access to that part of the dashboard, or maybe we can do some kind of human redaction. TBD.
