I created a module for dayli stock moves(Initial Stock, In, Out, Final Stock) and need filter by today, specific date and range o dates. But this don't show the search in my tree view. What is wrong?(Sorry for my english)

This is my module(stock_picking_extra.py):

class stock_moves(osv.osv):
_name="report.movimientos.stock"
_auto = False
_columns = {
    'date': fields.date('Fecha', readonly=True),
    'product_id': fields.many2one('product.product','Producto', readonly=True),
    'qty_inicial': fields.float('Inicial', readonly=True),
    'qty_in': fields.float('In', readonly=True),
    'qty_out': fields.float('Out', readonly=True),
    'qty_final': fields.float('Final', readonly=True)
}
_order = "date DESC"
def init(self, cr):
    tools.sql.drop_view_if_exists(cr,'report_movimientos_stock')
    cr.execute("""
        CREATE OR REPLACE VIEW report_movimientos_stock AS 
            SELECT movimientos_stock.id, movimientos_stock.date, movimientos_stock.product_id, movimientos_stock.qty_inicial, movimientos_stock.qty_in, movimientos_stock.qty_out, movimientos_stock.qty_final
            FROM movimientos_stock() movimientos_stock(id, date, product_id, qty_inicial, qty_in, qty_out, qty_final);
        """)

stock_moves()

My filter (stock_picking_in_view.xml)

<record id='movimientos_stock_filter' model='ir.ui.view'>
        <field name="name">movimientos.stock.filter</field>
        <field name="model">report.movimientos.stock</field>
        <field name="arch" type="xml">
            <search string="Moves">
                <field name="date" string="Fecha de Movimiento" filter_domain="['|',('date','=',self)]"/>
                <filter string="Mayor que" name="may_q" icon="terp-accessories-archiver" domain="['|',('date','>',self)]"/>
                <filter string="Menor que" name="men_q" icon="terp-accessories-archiver" domain="['|',('date','>',self)]"/>
            </search>
        </field>
    </record>

My tree (stock_picking_in_view.xml)

<record model='ir.ui.view' id='movimientos_stock_tree'>

                <field name='qty_final'/>
            </tree>
        </field>
    </record>
