When I login with admin , I can see all sale order. But with portal user, only see  orders under same company with him. When I check domain for this, I only see following domain.But I think that is not difference between admin and portal.So, how it's work.

domain = [
            ('message_partner_ids', 'child_of', [partner.commercial_partner_id.id]),
            ('state', 'in', ['sale', 'done'])
        ]

I want to filter like even portal user are same company, I want to display his orders only.I add the following domain.I display his order but the main problem is admin can't see all order.How can I do that?

domain = [
            ('message_partner_ids', 'child_of', [partner.commercial_partner_id.id]),
            ('state', 'in', ['sale', 'done']),('partner_id','=',request.env.user.partner_id.id)
        ]
