Imagine my repo tree looks as follows:
MyProject
|-----foo
|-----bar
|---baz
|---etc...
When i try to search for a word in files with specific extensions in bar/baz i set the files to include field to .h, .cpp, bar/baz/.
VS code seems to ignore bar/baz/ but it works when i set a path with project dir (./MyProject/bar/baz) or delete extensions (.h, .cpp).
