Matched against the product name in the page address, e.g. milk, bread, coffee. Accents, capitals and punctuation don't matter (québon finds Quebon and Québon), and a term with several words, such as chips ahoy, finds products that contain all of them, in any order. Any term can match. Each word is matched anywhere in the name, so short words catch more than you expect ('com' matches 'compliments'); products where the word stands on its own come first. Names are mostly in English; common French grocery words (lait, fromage, biscuits) also find their English word. Every match is listed, free, under Storage → MATCHES. Leave empty to walk the whole catalogue.
