Why showing everything you know when you have the right answer?
That is at least what the team at Google thinks when updating its search engine. Here, Google can show answers to some specific queries without a doubt and without any additional search results.
So for example, if users search for [time in jakarta] or [time in indonesia], Google can show the exact answer without showing anything else like it usually does.
The rest of the results however, is hidden unless users click on the 'Show all results' below the answer.

According to Google, users that search for this type of query, "rarely use full search results."
So indeed, if users just seek for one obvious answer, why should Google bother to show more? After all, this creates simplicity for users to get the very answer they need, quick and easy.
The feature also works for calculator query types as well as conversions, as shown below:

Google calls this 'Zero Result Search', and it's how its search engine can answer queries without showing any organic listings or ads.
The feature works on both desktop and mobile, and reflects Google's Danny Sullivan that said it was all about providing the fastest results where they don’t believe searchers really want additional results, such as when they just need to confirm the current time, or they are wanting to use a calculator.
Google keeps monitor about this feature's usage, and there is an feedback links at the bottom of the answer for those who like to say something back to Google.
