Vim searching through all existing buffers

Question

When dealing with a single file, I'm used to:

/blah
do some work
n
do some work
n
do some work

Suppose now I want to search for some pattern over all buffers loaded in Vim, do some work on them, and move on. What commands do I use for this work flow?

Answer 1

Another approach:

:call setqflist([])           " clear quickfix list
:silent bufdo grepadd! foo %  " edit foo in command-line history window
:cw                           " view search results

Or mapped:

cmap bbb call setqflist([]) \| silent bufdo grepadd!  %<C-F>$hha

Answer 2

I would open all the buffers in a new tab using the following two commands:

:tab sp
:bufdo sp

Then search through each file one by one and close its window when you are done (use :q or :close). Use CTRL+W_ to maximize each window as you are working in it. When you're finished and you close the last window, the tab page will close and you'll be dropped back wherever you were before you decided to do the search.
