vim — How can I search buffers?

I am looking for some command like:

:b1!g/something_here/

where I supposedly search for a word "something_here" in the buffer "b1". How can I do it?

From stackoverflow

• Well, go to buffer b1 and

  :g/something here/
  

  For searching through all open buffers there are various plugins, for which I think would be best if you took a peak on www.vim.org

  Edit: like this one - buffergrep
  And my personal favorite for all kinds of searching: compview

• I often do:

  :rew
  :bufdo 0
  :bufdo g/something here/
  :ls
  

  The last :ls allows me to see all the buffers that are not positioned on line 1

  Masi : Thank you. the command ":bufdo" is useful. +1

• You can try something simple: :b0 |?somethingToSearch
