You can use this code( it will add the new fields if they don't exist and update them if they exist already).

doc.reference.update({
                u'newField1': newValue1
                u'newField2': newValue2
            })

You can only have one value per field name. Merge is useful when you want to add additional fields to the same document, for example:

 data = {
    u'name': u'Los Angeles',
    u'state': u'CA',
    u'country': u'USA'
}

db.collection(u'cities').document(u'LA').set(data)

city_ref = db.collection(u'cities').document(u'LA')

city_ref.set({
    u'name2': u'MIAMI',
    u'state2': u'CA',
    u'country2': u'USA'
}, merge=True)

# Result

data = {
    u'country': u'USA',
    u'country2': u'USA',
    u'name': u'Los Angeles',
    u'name2': u'MIAMI',
    u'state': u'CA',
    u'state2': u'CA',}
