Question

Hello.
I have a small business editorial office, the question is: how to make products that are out of stock not displayed in the catalog, but indexed by search engines?

Answer 1

Set a filter on the catalog.section component.
Filter example:

array(
    '>CATALOG_QUANTITY' => 0
)

Write this filter to a global variable and pass the name of this variable to the FILTER_NAME parameter when calling the component.
Thus, these products will not be shown in the list of products, but will be available via a direct link.
