Add new search field in Product search page

Hi Expert,

Please help.

I need to add few search Zfield in the Product search page(Component PRD01QR/ Search View  and BOL Query object : ProdAdvSearchRgProducts).

These new zfield are the set type which already display in different assignment block in the Overview page of Product.

Somehow i understand to add zfield(set type) in the search view but ques is how can we filter the entities based on the newly add zfield(set type).

Please note these newly added field are the set type which use in the assigment block in the overview page.

I have search lots of thread but non of the thread provide full explaination.

Thanks,

Rajan
