Searching through Cunnan isn't hard. If you type something into the search box at the top or bottom of an article then click the "Search" button you'll be taken to a list of all articles that have the words you entered in their titles or contents.
If this search doesn't find what you want then you might not be searching in the right places. On the page with the list of articles that appears after you search there is a box (near the bottom) which you can use to refine your search. You could, for example, limit your search to pages about Cunnan or to pages about Cunnan's users.
