During May 2025, David Causse enhanced the wazuh/wazuh-indexer repository by delivering matched fields support to the unified highlighter, enabling search snippets to blend matches from multiple fields for improved relevance. He implemented this feature in Java, updating both the changelog and test coverage to ensure robust integration. Additionally, David addressed resource management in S3 repository tests by refining executor service termination within S3Service and S3AsyncService, which improved test reliability and prevented thread leaks. His work demonstrated a strong grasp of Java, Lucene, and OpenSearch, focusing on both feature development and the maintainability of the testing infrastructure.
