I'm converting from Textmate to MacVim and I'm struggling with replicating Textmate's 'Find in Project' feature. I can search just fine with `:vimgrep /foo/g **/*.py` and open the quickfix window with `:cope`. From there I can navigate to and open the appropriate match without issue.

My problem is that if the match I opened isn't the correct one, I can't find a way of bringing back the search results window without running the entire search again. I can open the quickfox window with `:cope` again but it only contains 1 result, the file I just opened.

What is the general workflow for searching multiple files and managing the results?
