>>> from io import StringIO
>>> from techminer2.thesaurus.descriptors import CreateThesaurus, ReduceKeys

>>> # Redirecting stderr to avoid messages
>>> original_stderr = sys.stderr
>>> sys.stderr = StringIO()

>>> # Create the thesaurus
>>> CreateThesaurus(root_directory="example/", quiet=True).run()

>>> # Reduce thesaurus keys
>>> reducer = (
...     ReduceKeys()
...     .where_root_directory_is("example/")
... )
>>> reducer.run()

>>> # Capture and print stderr output
>>> output = sys.stderr.getvalue()
>>> sys.stderr = original_stderr
>>> print(output)
