Point Of Sale - Order Product Search

This module extends the search options on the Point of Sale Orders screen. It does not add new menus or models; it only adds extra search fields to the existing filter panel.

On the POS Orders list (the screen where you review past point-of-sale transactions), the search box now offers three additional fields:

• Product: type a product name to find all orders containing that product.
• Product Barcode: type or scan a barcode to find orders that include the matching product.
• Product Reference: type the internal reference of a product to find orders containing it.

All three searches look inside the order lines, so they match orders based on the products sold, not just the order header. The matching is partial and case-insensitive, so typing part of a name or reference is enough.

This is useful for quickly locating a sale when a customer returns with a product but no receipt, or for checking how often a specific item was sold. The module only changes the search interface; it does not alter order creation, pricing, stock or accounting behaviour.
