Aptitude ?narrow search

[Panayiotis Karabassis <panayk@gmail.com>]

Hi! Is it possible to combine multiple filters in a ?narrow aptitude search.
For example to search for package where a single version matches all of 
?A, ?B and ?C.
To illustrate suppose I want to search for package where a single 
version matches  "~A^unstable$",  "A^stable$" and "~i". A search where 
we expect no results. Yet:

$ aptitude search '~S (~A^unstable$~A^stable$) ~i'
[...]
i   time                            - The GNU time program for measuring 
cpu res
i A tsocks                          - transparent network access through 
a SOCKS
i   twm                             - Tab window manager

$ aptitude search '~S ~A^unstable$ ~S ~A^stable$ ~i'
[...]
i   time                            - The GNU time program for measuring 
cpu res
i A tsocks                          - transparent network access through 
a SOCKS
i   twm                             - Tab window manager

Thanks,
