What happened, and what did you expect?

The README documents name_pattern as a regex (--name-pattern '.*Handler.*'), so I assumed file_pattern was one too. It isn't. It's a glob, and a regex pattern returns 0 results with no error.

--label Function                           -> total: 13006
--label Function --file-pattern '.*src.*'  -> total: 0
--label Function --file-pattern 'src/*'    -> total: 2162

Poking at it, the glob looks restricted. * and ? both work and cross /, [a-z] matches nothing, and matching is case insensitive: SRC/* returns the same 2162 as src/*.

tools/list returns an empty description for file_pattern, name_pattern and qn_pattern, so there's nowhere to look this up short of guessing.

Documenting the syntax would be enough. Rejecting patterns that contain regex-only characters would be better, since a zero here looks exactly like a real "nothing matched".
