There are reports (see link below), that Google will now stream a small set of apps, when content in those apps match your search criteria. I have yet to be able to produce a Google search that shows one of these streaming app results.
I've tried using the example that I've seen in articles: "hotel right now in Chicago", from both the mobile web version of Google.com, as well as the Google app, but to no avail. The correct answer to this question will look something like:
"In order to see a streaming app result, you must be within the Google App, and you must use the following search: What is Sagittarius' horoscope for today?"
It appears from this link (www.example.com/GooglePulledStreamingApps) that Google is no longer streaming apps, or is only streaming them to a limited number of people.
I've also discovered (see 2) that this only works from the Google App on devices running Android 5 or 6. Although this feature of Google is only available on Android, I still don't believe this is an Android Community question, because it is specifically regarding how a search on Google behaves.
What are streaming app results?
