You are building a question and answering system. You retrieve documents from a corpus given a question text. A large language model generates an answer based on these retrieved documents. What is this architecture for answering questions commonly called ?

Which of the following metric tends to fluctuate i.e. may increase or decrease as we go down the ranks of the set of retrieved documents in an information retrieval system ?

You are an engineer who has to build an information retrieval system for a doctor. The system can only retrieve a fixed number of documents at a time after which there is a long waiting period until a new set of documents can be retrieved. You want to minimize the time taken for the doctor to retrieve the most relevant document for their query. Which metric are you going to optimize to achieve this ?
