Yes, there is. You can use search using the following:

    <keyword> user:me

This will search for answers (and questions) by you that contain the word `<keyword>`.

Here's an example of looking for the word `local` in answers by me:

 ![][1]

You can pretty much use this for everything else in the search. For instance, you can use it to search for questions of a specific tag by you using `[tag] user:me`. This will display all questions/answers by you on questions that were tagged with `tag`.
