Developed and integrated Aliyun as a new search engine option for the PAI-RAG repository, expanding enterprise search capabilities and enhancing configurability for multi-engine scenarios. The work involved backend development using Python, focusing on API integration with the Aliyun search API through the creation of the AliyunSearchTool. Updates included implementing UI support for Aliyun credentials and adjusting configuration settings and dependencies to enable seamless Aliyun-based searches. No major bugs were reported or fixed during this period. The contribution demonstrates depth in full stack development and cloud services, addressing vendor flexibility and preparing the platform for broader enterprise search requirements.
