How can I duplicate the searchbar? I'm trying it like this with a new modul

I want to have a second way to filter the (product attributes from variant products in the sale.order)

It should be simply and not with to much clicks or too much time waste to select a filter for example: attributes.

So I think to make a second searchbar would be the best way, so that this one has only 1 filter attribute , so I can filter the product variants easly....

I'm searching for a way to make a simple search field with 1 filter="attributes" for all products variants.
