You still got the same problem there about which I told you a week ago. "EN--1000-0003-3" is not the same as "EN-1000-0003-3". Don't you see that in file there are two "-" after the EN, whereas in the search string there is only one "-".

To make it even more obvious:

EN--1000-0003-3    is not the same as
EN-1000-0003-3
