"I don't want this ------, but this is good GC-113, AO-1-GC-113, AO-2-GC-113"
BUT if I come across one where there is no space between the number, but just another character like a comma or a period then it returns a match on the entire section "GC-113,AO-1-GC-113,AO-2-GC-113"
"I don't want this ------, but this is good GC-113,AO-1-GC-113,AO-2-GC-113"`
