Default [Q] Set Google search to search only on phone by default

Hi, i often use google search to search the name of apps instead of using the drawer. I've enabled the search on local phone, including app, chrome and contacts. When i type an app name, i got at first (on top) the name of the app, and when i'm going to tap on the icon, three suggestion from web appears on top, and the app goes down. The beavior is very variable, because of the presence of internet connections (in such case no suggestions) and its delay (mobile data vs. Wifi).
It's really annoying beacuse i use the search to open the app quickly, and often i click on the randomly popping-up suggestion, which open Chrome, etc.. (at the end is anything but quick).

There's a way to disable these suggestion, or use directly the phone (local) search?
Thank you.
