Above the DRUG search field, there are four options that allow you to adjust the filtering parameters that are used when searching for a drug. You can cycle through these by pressing F8 on your keyboard.
RECENT: This will show all the products recently dispensed.
ACTIVE PRODUCTS: This will show all Products that are marked as active
GENERIC SEARCH: This will search by the Generic name of the item, e.g. Searching Paracetamol will bring up all products containing Paracetamol.
BRAND/GENERIC: This will filter the search to both the Brand Name and the Generic Name of all products.
