Developed built-in term ID remapping for sparse vocabularies in the SINDI index within the antgroup/vsag repository, enabling robust support for non-contiguous term IDs. The work involved designing algorithms and data structures in C++ to handle remapping efficiently, with careful attention to memory management and performance under heavy workloads. Addressed a rerank path issue to ensure accurate distance computations by referencing the original query when remapped IDs are present. Expanded unit testing to cover remapping scenarios, including quantization, filtering, and reverse mappings, and introduced memory and performance assessments. Code quality improvements included style refinements and maintainability enhancements throughout the codebase.

May 1, 2026May 2026: Delivered built-in term ID remapping for sparse vocabularies in the SINDI index for antgroup/vsag, enabling robust handling of non-contiguous IDs and extending sparse vocabulary support. Also fixed a rerank path bug to ensure distance computations use the original query when remapped IDs are involved, improving result accuracy under remapping scenarios. Expanded test coverage with comprehensive remap tests (quantization, filtering, reverse mappings) and functests, and added related memory/performance assessments. Implemented memory-management refinements and pre-allocations to improve stability under heavy workloads. Code quality improvements included clang-format/style fixes and maintainability enhancements.
