The workflow connects to a Supabase vector store to perform multi-level retrieval. It first searches file descriptions to filter relevant files, then performs vector searches within those files to fetch precise results. This reduces irrelevant data, improves answer accuracy, and optimizes performance when dealing with large document collections. The integration with OpenAI ensures that the filtered document chunks and associated metadata are used to generate comprehensive AI-powered answers.
