How to search the Specific category of the product in the "Sales->Product" Module.
Example:-
Three cell phones(Nokia,Apple & Samsung) while clicking on "Group By -> category" option it is showing three categories Named (Nokia,Apple & Samsung) I need to search only mobiles in the 'Nokia' but not remaining but, if I am searching for any thing in the search on the top right in the "Odoo->Sales->Product " it is searching for the remaining category 'Apple & Samsung'.
But I need to search only in one specific category like only in Nokia.
Can any one suggest next step to achieve this task......
