A few weeks ago, Google revelled the new update about no search result on the SERPs. Google called it Zero results. This applies to queries based on calculation, conversions, and time queries. But after a hot debate on Zero results with many examples of problems cover this implementation. Finally, Google has reverted this, and now there is no longer showing zero search results.
Google said that after getting lots of feedback, they conclude that the condensed view experiment should stop for now. Team is working to improve it more.
This statement of Google shows that this may come back with another version.
