How to search only files that have a particular directory name anywhere in the path?

[learnbyexample]

Sample file structure:

$ touch ip.txt f1.txt
$ mkdir -p foo/baz abc/ijk/baz/qq baz/123 qq/baze
$ touch foo/baz/f2.txt abc/ijk/baz/qq/f3.txt baz/f4.txt qq/baze/f5.txt

$ rg -V
ripgrep 12.1.1

$ rg --files
ip.txt
foo/baz/f2.txt
f1.txt
baz/f4.txt
qq/baze/f5.txt
abc/ijk/baz/qq/f3.txt

How do I search only paths that have baz as a directory name? Here's my attempts with -g option:

# globstar is enabled, so this gives the directories I want to search
$ ls -d **/baz/
abc/ijk/baz/  baz/  foo/baz/

# no match
$ rg --files -g '**/baz/'

# only one match
$ rg --files -g '*/baz/*'
foo/baz/f2.txt

# only two matches, abc/ijk/baz/qq/f3.txt is missing
$  rg --files -g '**/baz/*'
foo/baz/f2.txt
baz/f4.txt

Well, as is the case often, I just tried this after posting the question:

$ rg --files -g '**/baz/**'
foo/baz/f2.txt
abc/ijk/baz/qq/f3.txt
baz/f4.txt

Is this the correct way to do this?

Yes. Although there are proposals in the issue tracker (IIRC) to have something simpler.
