How to filter the orders on the field "External ID"directory?

In the list of orders of administrative panel there is a field "External ID" directory, that allows you to track which of the directories is the order. However, among the filters, there is no such field. Need to filter orders belonging to one of the directories. How can I do that?

@Queenie.Lebsack from the first words is unclear:

in the array $arFilterFields add SV-in Created by (CREATED_BY)

Where this array is filled in? - ezra_Wilkins commented on March 23rd 20 at 19:14
