With their site, you can search by author, title of blog, blog description, category, language, and keywords. Plus if you click on the name, title, or language (on the top of the page) then the list is automatically sorted in ascending order, click again and the list is automatically sorted in descending order. Not only that, but if your site is not on there, then you can quickly add it. If your site is on there and it needs updated (due to name change... etc), you can update it with a single click. In addition to that, you can even put the list on your site. You have all kinds of options on how you would like the list to be displayed as well.
