sourceAttributes property
An optional list of source attributes that provide data for this index
field. If not specified, the data is pulled from a source attribute with the
same name as this IndexField. When one or more source
attributes are specified, an optional data transformation can be applied to
the source data when populating the index field. You can configure a maximum
of 20 sources for an IndexField.
