There's no real reason to send multiple ANS's in this situation. 
Multiple ANS's are best used when there are multiple independent answers 
that might be returned in arbitrary orders. If you're getting back 
exactly one answer, a RPY is appropriate. If you can send a message that 
says (for example) "send me back all the text files", then mutiple ANS 
frames would allow the blocks of the different files to be interleaved, 
so the files can start being sent back as they're found, without one big 
file holding up many smaller files.
