Adobe Indesign Find Change Item Numbers?

Question

I am using Indesign CS5 on iMac, running OS 10.8.3.
I designed a product catalog that has 148 pages. Now I need to save the same design and make a new catalog for our wholesalers. On the wholesalers catalog I need to change the item numbers and add FC in front of each item number. How can I use find change to find each item and change them with FC in front of the item numbers? The following are a few examples of the item numbers:
LED-4042 I want to change it to FCLED-4042
UA-42 I want to change it to FCUA-42
SC-110 change it to FCSC-110
KN-10 change it to FCKN-10
etc....
I am hoping there is a fast way to find and change these. I was looking in to GREP, but I could not figure how to do this.
Thanks,
Omar

Answer 1

This could be a very complex GREP - or a very simple one.
4 Examples are good, but we need more concrete examples. In particular, the longest and the shortest example.
LED-4042 I want to change it to FCLED-4042
UA-42 I want to change it to FCUA-42
SC-110 change it to FCSC-110
KN-10 change it to FCKN-10
This will find your posted item numbers - but …
\<\u{2,3}-\d{2,4}
change to:
FC$0
AND: exists one or more item number/s with FC at the beginning? I hope it is not so.
<edit>
A new day, a better solution (This GREP can be used many times in succession. It may already one or more "FC-numbers" be present.):
\<(?!FC)\u{2,3}-\d{2,4}\>
Or if no similar strings are exists in your document:
\<(?!FC)\u+-\d+\>
Have fun and give a feedback.
