Search for Products in Order Creation?

Hello, this is a “pre-install” question. I want to speed up the search bar not only in the Orders section, but also in order creation (Edit/Add Order) where there’s search bars for assigning Customers and adding Products. My client’s website suffers from prolonged search time and crashes, especially the Products.

Can you use this to speed up search in order creation? I’ve been looking forever for a solution but haven’t really come across an “Add Product Search” plugin. Thank you!
