There are several threads with NCO in the title, but searching for NCO returns 0 hits. Maybe the indexes need to be rebuilt? I am having a bear of a time finding threads on NCO and they are so big, I know there are people out there asking and answering issues with this CA.
As CCN Mod said, the search feature won't let you search on a "word" of 3 letters. NCO Financial is probably not a good key word, as most of us are too lazy to have ever typed that out . However, if you throw in the wild card asterisk, you get past the 3 letter problem. (NCO*). I came up with 123 hits.
