Difference between "query_topics" and "add_documents"?

[dror-kris]

Hi, I have trained a model on half of my large corpus and want to analyze the rest of my corpus using the existing model.

As far as I understand there are two possible methods to doing this - either running a query_topics() over each individual document, or adding the list of new documents via add_documents().

What is the difference between the two?
