Worked on the opensearch-project/k-NN repository to address a stability issue in nested kNN searches, specifically targeting NullPointerExceptions when segments contained documents with missing nested objects. Developed the NestedKnnUtil utility to introduce pre-checks for parent documents, enabling the search process to gracefully handle segments without vectors and return empty results as needed. Enhanced the codebase by centralizing constants and utilities, which improved maintainability and reduced duplication. Expanded both unit and integration test coverage across Lucene and Faiss engines, including byte and float vector scenarios, using Java and OpenSearch to ensure robust, engine-agnostic behavior and safer production deployments.

Jun 1, 2026June 2026 — opensearch-project/k-NN: Implemented a stability fix for nested kNN searches to prevent NPEs when segments contain documents with missing nested objects. Introduced NestedKnnUtil with a pre-check for parent documents, and updated query paths to gracefully return empty results for segments without vectors. Expanded test coverage with comprehensive unit and integration tests across Lucene and Faiss engines, including byte and float vector paths and MOS Faiss scenarios. Refined code structure by centralizing constants and utilities to improve maintainability. Result: increased reliability of nested kNN results, reduced production risk, and stronger engine-agnostic behavior across search paths.
