As far as I can tell there's no predictive search. UI is a simple search box, optional country selector dropdown and an "Only search in cache" checkbox. Smoke test shows the cache checkbox works - apparently nobody else has searched for "dog" in the US. The country dropdown is interesting as far as the cache goes - not selecting a country is meaningful as far as the cache is concerned. My prior "dog" query in the US does not return hits if I don't select a country. Not selecting a country and searching the cache appears to return english results (with a few sample searches). It's interesting that you can explore the cache with this checkbox. Not sure if there are any privacy concerns with this feature - considering cache searches are "free" you can kind of scrape what other users are searching for, maybe with enough users it doesn't really matter. I suppose there could be rate limiting and such to prevent this kind of attack, but that's just a guess. It may be useful to have an option to opt-out your search from cache.
