I have the same issue with the search. Search by order number doesn’t work. I am using plugin “WooCommerce Sequential Order Numbers” but I have custom order number. It looks like: #0324-3069, where the first part is MMDD. Search gives me nothing if I put, for example “0324”. But I know order #0324-3069 exists.
My site:
WordPress – Version 5.3.2
Woocomerce – Version 3.7.1
WooCommerce Sequential Order Numbers – Version 1.9.4
