  /**
   ENTERPRISE EDITION ONLY : DEVELOPER PREVIEW
   
   The predictive index used for querying with prediction function. The predictive index
   is different from the normal index in that the predictive index will cache the prediction
   result along with creating the value index of the prediction output properties.
   
   The PredictiveIndex can be created by using IndexBuilder's predictiveIndex() function.
   If the prediction output properties are not specified, the predictive index will only cache
   the predictive result so that the predictive model will not be called again after indexing.
