There is not a specific search for "your" answers - even in the earlier incarnations of the forums here.

Currently, if you go to advanced search, you can refine the search with your account name under "Author Name" and then set the Question Status to "Answered".  This will produce a search result of all of the answered threads in which you participated.  No guarantee that you were actually the one that was tagged with the answer mark though.  I think this is as close as you will get to what you are looking for.
