I don't know if it's possible to search for "A^J^J" using find+grep, and 
it's the implementation choice for this function.

On the one hand, it limits the variety of the regexp you can use. On the 
other hand, you can get results faster, and you can search inside 
directories (dired-do-search only searches within regular files and 
silently skips any marked directories).
