Does anyone know how to Hide Certain Products from search bar in shopify store?

This didn’t work for me. It look a little different now, asking if you want to expose it to an API, if you want 1 value or a list of values… I set it up right, went to edit the product I’d like to be hidden from the search, & entered the number 1 in the metafield, but it still shows in a search. Anyone know what I’m doing wrong here?
