There we go, another perfect example: https://www.sainsburys.co.uk. Search for "walkers". Enjoy two pages of Walkers products randomly intermixed with other crisps. You'd like the "Walkers Baked" variety? Searching for that returns 2 results, instead of the expected 4+. Example missing result: https://www.sainsburys.co.uk/gol-ui/product/walkers-baked-se.... Now try searching for "Walkers Baked Ready", different UI (???), same two results, but this time what we're looking for is in the "suggested related products".

How do companies tolerate such obviously awful search experiences?
