No more sold products should not be available for search

[alexgarel]

What

We promise to producer that if they mark a product as "taken off the market" they should not be found doing a search. But as you search them, you find them.

Steps to Reproduce

1. Go to https://world.openfoodfacts.org/product/3760307950145/la-jucerie and see that it is "taken off the market"
2. Go to front page and search "jucerie"
3. you see the product in result page

Expected behavior

The product should not appear in a search (but maybe, a search on barcode). Still, it should be reachable by its url.

I would like to work on this issue @alexgarel

[alexgarel]

@aakankshabhende this might be a difficult issue, just because the codebase is large ! Also because it's a bit controversial, and I think to make this resolution acceptable we should also add a "include unsold products" checkbox on the advanced search, and/or display the number of hidden unsold products on a search.
