Doing that requires editing the quickfix list. Refer to the thread
you started April 27, "quickfix window's manual fix", for possible
solutions.

The only other way I can think of to do this is to set your
'grepprg' to "cscope" plus a few cscope options, piped into grep to
select those results matching your filename pattern.

I used to execute cscope searches using :grep and the performance
was pretty good.

Those are my thoughts, but I don't have a canned solution for you.

Do you want to eliminate non-matching entries from the list, or just not
switch to them?

just not switching to them will work for me too. i'm aware that there
are functions like getqflist() to
manipulate on the quickfix results. but i'm not too sure if i can
update that list. i thought there might
be some easier solutions that folks might aware of.

There was a message here, that mentioned a plugin that allows you
to modify the quickfix list:
http://groups.google.com/group/vim_use/msg/d622507cbf73a697

So you might want to try this plugin.

If you are willing to browse using the quickfix window rather
than :cnext and :cprev and the like, it's easy to simply fold away
everything you're not interested in:

There was a recent thread where somebody wanted to jump between just
errors, or warnings, or info messages in qf, but the OP seems to have
gone AWOL. However, in that thread, I was thinking something along these
lines would work:

command! -nargs=1 QFNextRegex call QFNextRegex(<f-args>)
command! QFNextError call QFNextRegex('error:')
function! QFNextRegex(regex)
" Gather info about the window state
let l:winnr = winnr()
let l:winrest = winrestcmd()
let l:lastwin = winnr('$')
" Use the error window to find the current error number
copen
let l:errnum = line('.') - 1
" Restore the window state
if l:lastwin != winnr('$')
cclose
endif
exec l:winnr . "wincmd w"
exe l:winrest
" Get the quickfix list
let l:qf = getqflist()
" Find and go to the next matching item in the list
let l:len = len(l:qf)
let l:errnum += 1
while l:errnum < l:len
if l:qf[l:errnum]['text'] =~ a:regex
exe "cc " . (l:errnum + 1)
return
endif
let l:errnum += 1
endwhile
" Give error if not found (hardcoded to English error message)
echoerr "E553: No more items"
endfunction

:QFNextError
:QFNextRegex \<mykeyword\>

I leave it as an exercise to produce the 'previous' version and/or
modify it to truly check the error type rather than just matching the
text and/or add commands for patterns useful to you. :-)
