You can use search phrases to filter products by any attribute such as id, category and type.
With WooCommerce POS you can search for product by title and also by attribute. For example, on the demo site a search for woo will filter by title, a search for cat:posters will filter products by the Posters category and a search for cat:posters woo will filter products by Posters category with 'woo' in the title. If you wanted to select the Movie Posters category you could use cat:"movie posters".
