During May 2025, Andrew Yu developed a CTE-driven Advanced Search Framework for the nasa/cumulus repository, focusing on enhancing the core search classes to support more complex and efficient database queries. Leveraging TypeScript, Knex.js, and SQL, he unified query construction across BaseSearch, GranuleSearch, ExecutionSearch, CollectionSearch, and RuleSearch by introducing new CTE builders, nested joins, and consolidated logic. This approach improved query performance, flexibility, and maintainability while enabling advanced search composition. Andrew also expanded test coverage and refactored key components, such as retrieveGranuleStats, to utilize the new framework, resulting in more accurate and performant metadata retrieval.
