Hi,

I need to have keywords in my product... and noticed the product_keywords in the search plugin and also in the export, but I cannot find where to populate this field on the product edit form.

Can you help? Where is the product_keywords on the product edit/entry form? How can I populate this field?

Thanks,

Dennis
