Search for orders by phone or e-mail
In the Opencart admin panel, the buyer's phone and e-mail does not appear in the order list by default, and there is no possibility of searching for orders by these fields This modifier eliminates this drawback.
What the modifier does:

Adds to the order list a fields with the e-mail and phone number of the buyer, and the ability to sort by this fields.

Adds order search field by the phone number and e-mail (or part of them).

The auto-substitution of fields: "Buyer", "Phone", "E-Mail" works correctly. Now the data for auto-substitution is taken from the database of orders. Without this modification, the data for auto-substitution was taken from the customer base, and therefore orders from unregistered buyers were not taken into account.

It is installed via OCMOD. No core OpenCart files are replaced.
