Hello, ziga32,
We have identified that the issue with the search functionality is related to product availability in stock. Currently, the option “Hide out of stock items from the catalog” is enabled in your WooCommerce settings (WooCommerce → Settings → Products → Inventory). As a result, any products that are out of stock are automatically excluded from search results.
If you would like these products to appear in search results again, please consider disabling this option.
Best regards,
The 8Theme Team
