This works well when the answer is stated in one passage or in several passages that are independently easy to retrieve.</p> <p>Some questions are harder because the useful evidence is connected by <strong>relationships</strong>, not just by similar wording. A developer may need to answer, &ldquo;Which service depends on the library maintained by the team that owns the payment API?&rdquo; No single chunk has to contain all of those words. The answer may require following several links across services, libraries, teams, and APIs.</p>
