Question-Answering-system-

The search (user's question input) interface and its output...

The model is predicting all the related tags that the user's question can be in. Note that the tags need not to be mutually exclusive i.e., a question can belong to multiple (overlapping) tags (topics). and then, we are retrieving the top 5 most relevant documents corresponding to that user's query.
