Shwethu Kannan developed a feature for the Yelp/nrtsearch repository that introduced a default recall limit for NRT Search, enabling more controlled recall sizes in search results. She implemented the defaultTerminateAfterMaxRecallCount setting, ensuring it was consistently applied across API requests, index states, and CLI commands. Using Java, Protocol Buffers, and gRPC, she added validation to prevent negative values, reducing the risk of oversized responses and improving resource utilization. Her work addressed the need for tighter control over recall results, demonstrating a focused approach to backend development and search technology within a short timeframe, with depth in both design and integration.
