I wrote a [Data Explorer query](http://data.stackexchange.com/stackoverflow/query/131059/search-answers-given-to-your-questions) that does this. You can search the body of answers given to your questions. 
As the data explorer gets updated weekly, this is a workable solution till advanced search gets an update (**if**).

It can also handle upper and lower limits for vote count of answers.

**Update :**

Now also handles accepted status of answers! (Enter 0 in `AcceptedAnswer` when searching for all answers and 1 when searching for accepted answers)
