Commerce orders - header
Did yout try simply add new filters? 

For example, user:


Add Filter Criteria
Chose Filter - User
Search for "name" field
Select "User: Name"
Check "Expose this filter to visitors, to allow them to change"
Click "Apply"


That's all you need to do. I should notice that for amount and date you can expose operator for your own needs.



In the same way you can add SORT CRITERIAS
