fields property
The fields supported by this index.
For composite indexes, this is always 2 or more fields. The last field
entry is always for the field path __name__. If, on creation, __name__
was not specified as the last field, it will be added automatically with
the same direction as that of the last field defined. If the final field
in a composite index is not directional, the __name__ will be ordered
ASCENDING (unless explicitly specified). For single field indexes, this
will always be exactly one entry with a field path equal to the field path
of the associated field.
