tags/search on specific files

[knubee <knubee@gmail.com>]

i would like to use some org-mode functionality for linking,
tagging, and searching files that are not specified in the
org-mode variables of .emacs file.

i thought that i would be able to create a file, work on it in
org-mode to create links and tags, and then be able to follow
those links and search on those tags.  after working on such a
file, linking works fine. but although running "C-c \" [tag]
does "highlight" lines that have the tag, it also displays all
the other items. (by contrast, "C-c a m" [tag] will display only
the specific tagged items for the agenda file(s) specified in
.emacs)

is there a way to do this that i am missing? either by providing
a file name as an argument or some other command that will return
such a view for the active buffer. (one reason i don't want to
add the specific file to the list of files that org-mode
automatically tracks is that i want to restrict my searching of
tags to specific files. but maybe i am not thinking about this
the right way.)

thanks.
