You can create a filter in search view, by inheriting the base search view of sale order ,and create a new view.

<data>
    <record id="sale_order_search_inherit_receipt" model="ir.ui.view">
        <field name="name">sale.order.search.receipt</field>
        <field name="model">sale.order</field>
        <field name="inherit_id" ref="sale.sale_order_view_search_inherit_quotation"/>
        <field name="arch" type="xml">
            <xpath expr="//filter[@name='order_confirmed']" position="after"> // Adding the filter after existing filter 'Confirmed Orders'
                <separator/>
                <filter string="Card Customer" name="is_card_customer" domain="[('partner_id.card_customer','=', True)]"/>
                <separator/>
            </xpath>
        </field>
    </record>
</data>
