How to use additional fields (keyword) for Item Search?

Summary:

On Part Requirements (or any other page) where Item can be searched, customer would like to be able to search for results beyond Item Number and Item Description.

Currently, when we search for Item, the part requirements page explicitly passes the ItemNumber and ItemDescription fields that should be searched against (screenshot below).

Item keyword is comprised of various data elements that business user can use to lookup an item, as looking up by Item Number and Description is not always ideal. Is there a way to extend this search to include keyword (or other attribute) in Service Logistics?
