Meihua Wu updated SPARK-9530:
-----------------------------
    Description: 
Currently the ScalaDoc for LDAModel.describeTopics and 
DistributedLDAModel.topDocumentsPerTopic suggests that these methods are  
approximate. However, both methods are actually precise and there is no need to 
increase maxTermsPerTopic or maxDocumentsPerTopic to get a more precise set of 
top terms.
