Try using the
custom vault search thingy I made. I did a quick search for CEP Portraits and got back 10 pages of results (ie way too many to list here). It didn't help that you didn't mention which version (CEP 1.x or CEP 2.x) you were looking for.
Anyway just download my search thingy, extract it to where you want and double click the resulting icon. Once the search (very basic) web page appears, enter what you want to search for just as you would on googles main page and wait for your results.
