    """
    Extracts a match enclosed in specified delimiters from the raw output.
    This function searches for text enclosed by a specified delimiter in the given raw output string.
    It returns the match specified by the `which_match` index. If no match is found, it returns "N/A".

    - raw_output (str): The raw output string to search within.
    - which_match (int, optional): The index of the match to return. Defaults to -1, which returns the last match. If the index is out of range, the last match is returned.
    - str: The extracted text or "N/A" if no match is found.

    Raises:
        - TypeError: If `raw_output` is not a string or `delimiter` is not a Delimiter enum value.
        - ValueError: If an unsupported delimiter is provided.

    Returns:
        - str: The extracted answer or "N/A" if no match is found.
