Worked on the apache/lucene repository to deliver storage of term vectors for FeatureField, enabling per-document feature access without runtime recomputation. This involved updating the FieldType to support the new storage capability and adding a new constructor to FeatureField, ensuring seamless integration with existing Lucene APIs. The implementation included comprehensive unit tests to validate the new functionality and maintain code reliability. By exposing feature data through stored term vectors, the work improved search relevance and analytics, supporting feature-based ranking and richer queries. The project demonstrated expertise in Java, Lucene internals, and search technology, with a focus on robust, test-driven development.
