How do i search a date field in my odoo search by the year in that specific date field.

It should be able to search the date field by only comparing the year part in the date field.

Eg:- I have dates like '01/04/2015','04/07/2016','10/10/2015' . I want to fetch the date field by giving just 2016 and it should retrieve me the last two document alone. 

I tried following options but didn't work.

<field name="date" filter_domain="[('date.strftime('%%Y')','=',self)]"/>

<field name="date" filter_domain="[('date.strftime('%%Y')','=',time.strftime('%%Y'))]"/>
