Hi,thanks for answering,
Im using "recommanded products" in the crossSeller options.
and then in the product admin page, i m adding products in recommanded product and using product search for that.
In fact, i had a weird thing this morning,
when i check the product section, i have 743 products (which is fine), and when i use "Product search" for the "first time" this morning, no filters, it displayed me 743 prods. (which was good :p)
i did a search (i wrote the product name), it didn't found it, i cleared criterias, did a search again and now i have 618 products...
Some products can be found (618) and the others are missing.
