Thank you for the details.
Okay, so I have tried the search for “132” and it returned 3 results. I clicked on this one, and opened the product editor screen. However I cannot see the custom field editor there, that contains the keyword “132”. Unfortunately the page is in hebrew, so it is a bit difficult to me to find it 🙂
Where is this value defined on the product editor screen? Do I need to turn on something to be able to see the keywords input?
Let me know.
