Two tools are available on the list:

1. Search box (placeholder Search): type any word — since the whole month's data is already loaded, this filters instantly against what's shown in each cell (order number, date, customer name, type, amount, subtotal, discounts, payment method, status, and kitchen location if that column is showing).
2. Column filters: the Date, User, Type and Status columns get a multi-select dropdown built from the values present in the loaded month; tick one or more values to narrow the table.

Because the list only contains the selected month, change the month first if the order you want was placed in another month.
