Vim: Difficulty setting up ctags. Source in subdirectories don't see tags file in project root

vim ctags

I'm trying to get setup with (exuberant) ctags on Vim today and am having difficulty getting it to work properly. I generate my ctags file on the command line with with:

cd myproj
ctags -R

This puts the tags file in myproj root. However, Vim only seems to read from this tags file when I'm working on source that reside in root. As I navigate to deeper directories, if I try to jump to a tag using <C-]>, I get:

E433: No tags file
E426: tag not found: MyClassName

I've verified that MyClassName does have a tag in the tags file, it's just that Vim doesn't see it. Can someone please explain how to configure Vim to reference the root's tags file?

Thanks.

add this to .vimrc file set tags=tags;/

This will check the current folder for tags file and keep going one directory up all the way to the root folder.

So you can be in any sub-folder in your project and it'll be able to find the tags files.
