                    and p.products_id <> :product_id AND MATCH('products_name') AGAINST (:products_name IN NATURAL LANGUAGE MODE);

Answer 1

I’d look at using MySQL Full-Text search.

This should be able to take the title of your chosen product and use it to retrieve relevant matches, eg

SELECT * FROM `products`
WHERE `id` <> :product_id -- don't return current product
AND MATCH(`product_name`)
AGAINST (:product_name IN NATURAL LANGUAGE MODE)

This requires you to create a full-text index on your products.product_name column.
