In April 2025, Xin developed the Tag Search and Filter feature for the OpenCSGs/csghub-server repository, enhancing user workflows by enabling efficient tag discoverability and filtering. Xin implemented backend search functionality using Go, leveraging LIKE queries on both the name and show_name fields within the database layer. The feature was exposed through an API query parameter, allowing flexible integration for client applications. Comprehensive test coverage was added to validate both matching and non-matching search scenarios, ensuring reliability. Xin’s work focused on API development, backend logic, and database management, resulting in improved data navigation and organization for tagging and asset workflows.
