dspy.evaluate.answer_passage_match¶

def answer_passage_match(example, pred, trace=None):
    """Return True if any passage in `pred.context` contains the answer(s).

    Strings are normalized (and passages also use DPR normalization internally).

    Args:
        example: `dspy.Example` object with field `answer` (str or list[str]).
        pred: `dspy.Prediction` object with field `context` (list[str]) containing passages.
        trace: Unused; reserved for compatibility.

    Returns:
        bool: True if any passage contains any reference answer; otherwise False.

    Examples:
        ```python
        import dspy

        example = dspy.Example(answer="Eiffel Tower")
        pred = dspy.Prediction(context=["The Eiffel Tower is in Paris.", "..."])

        answer_passage_match(example, pred)  # True
