Android Google widget: Searching just apps on the phone/device

Long version:

I recently upgraded from a Nexus 5 to a Samsung Galaxy S6. One thing that bugged me from this change was the way the Google search widget behaved. The Nexus 5 would present content on the device as quick results as you type the search phrase. This is what I used to quickly find apps and open them. On the S6 it would search the web, music, contacts, books and apps.

Short version:

To configure the Google search gadget to present apps as quick results:

Open up the apps tray.

Open up the Google folder and/or find "Google Settings".

Open up "Search & Now".

Open up "Phone Search".

Now you can select what the Google gadget searches.

I've only got "Apps" and "Contacts" selected. But it's up to you how you use this widget
