Worked on the infiniflow/infinity repository to enhance full-text search and indexing capabilities, focusing on both performance and reliability. Delivered features such as output path restructuring, a whitespace analyzer with customizable delimiters, and BlockMaxWand-based optimizations for phrase search. Addressed bugs affecting secondary index range queries and merge-limit behavior, improving accuracy and resource efficiency. Applied C++ and SQL to refactor core components, streamline memory management, and optimize query execution. Emphasized backend development and database internals, implementing column-aware filtering to reduce I/O. The work resulted in faster search throughput, lower resource usage, and improved scalability for large-scale text datasets.
