Currently the way Insite search works in Order History, the customer has to match the ENTIRE order number. Example: 123456-01. If a customer searches for 123456 (without the -01) it says no results found.
This should work the same as regular site search. If the customer searches for 123456 it should find the order 123456-01 because it is matching part of the order #.
This is going to be a frustration for our customers. We will have to teach to enter the ENTIRE number until this is fixed.
