getFields
The fields supported by this index.
For composite indexes, this requires a minimum of 2 and a maximum of 100
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.
