Hello Mahi,
Navigate to the Odoo Website Shop Page;
Click on the Customize tab and then enable Product's Attribute Filters; from here you can set the filters on the basis of product's attribute.

Moreover, you can also look into Odoo Website Advance Search module. 
The products can be filtered on the basis of category, attribute, name, and product SKU.

Regards
