Shoppers see matching products as they type, in a dropdown under the search box. We never request theme write access; check the permissions screen before installing. The search box is a theme app extension that you place yourself, so nothing is written to your files. Your catalog is indexed the moment you install, so search works right away. Searches that come up empty are reported back to you, and you can fix them with synonyms so the next shopper finds the product.

• Your catalog is indexed at install, so search works as soon as setup is done
• Typo tolerant and accent aware: “cafe” finds “café”, “shose” finds shoes
• Set synonyms so the words shoppers actually type find the right products
• See which searches came up empty, so you know what your catalog is missing
