Limit articles base on special header

[Steven Woody]

i've use 'B c' copied some newsgroup articles into my nnml inbox for further
reading. but late, i found it's hard to pick out them out of my hundreds of
normal messages.  so i want some kind of limit/search function on the inbox
folder. but it seems not exists in info page.

those messages i want to pick out all have a special header 'Newsgroup:'.

any idea? thanks.
