    into a sequence of trie ranges of the form ``(start, end, shift)``. The
    consumer of these tuples is expected to shift the ``start`` and ``end``
    right by ``shift``.

    This is used for generating term ranges for a numeric field. The queries
    for the edges of the range are generated at high precision and large blocks
    in the middle are generated at low precision.
