Vista - Need help with Windows Mail search

I need some help using Windows Mail search. In XP and Outlook, I could
easily search for a specific message or author. I could quickly move from
one entry to another with a single keystroke (but have forgotten what that
was). I could do this to move through the list of message threads and
therefore could also see all of the responses. With Windows Mail search, I
can go to the message or author, but all results end up as single entries in
the search engine, and I cannot easily see the sequence of response. It is
very awkward, and it is often difficult for me to locate the original
message if I want to scroll through the newsgroup threads.

I hope my description makes sense. Can anyone give a workaround to get the
same type of information as I could quickly obtain under XP? I am using
Vista Home Premium.

Thanks,
