What is the APK (and package) name of the Google App?
Answering my own question, thanks to the method found on this View app's full package name? thread and the hint provided by Google App's URL in Google play.

I typed:

 adb shell 'pm list packages -f searchbox'


And received:

package:/data/app/com.google.android.googlequicksearchbox-1.apk=com.google.android.googlequicksearchbox
