I am trying to search for a document based on the Customers Purchase order. I enter the PO into the search box with the type of search set to "contains". Nothing comes up. If I enter a part number into the search box, all the documents with that part number are retrieved. Is the search box limited to searching specific fields in the document? I'm looking for PO 90I8141 for my customer Nexteer, and all of the order numbers are effective. As an example, Order# 20190716-001 can't be found by searching for the customer PO number contained in the document.
