Before Change

    org_bool = df_empty["rec_id"].str.endswith("org")

    // merge the two frame and make MultiIndex.
    pairs = df_empty[org_bool].merge(df_empty[~org_bool], on="key")
    pairs_mi = pairs.set_index(["rec_id_x", "rec_id_y"]).index
    pairs_mi.names = [None, None]

    return pairs_mi

After Change

    index = df.index.to_series()
    keys = index.str.extract(r"rec-(\d+)", expand=True)[0]

    index_int = numpy.arange(len(df))

    df_helper = pandas.DataFrame({
        "key": keys,
        "index": index_int
    })

    // merge the two frame and make MultiIndex.
    pairs_df = df_helper.merge(
        df_helper, on="key"
