How to exclude file patterns in vimgrep?

Question

In vim, I do search with vimgrep frequently. I have mapping like below:

map <leader>s :execute "noautocmd vimgrep /\\<" . expand("<cword>") . "\\>/gj **/*.*" <Bar> 
cw<CR> 5

The problem is that there are some temporary subfolders (like obj, objd) that I don't want to search for. How can I exclude subfolders matching given patterns. For example, subfolders with prefix "objd" should not be included in searching.

You could try ack instead. It integrates nicely with vim and has lots of options for doing the sort of thing you want to do.

There are several ack-vim integrations on GitHub. For example: here and here.
