Designing metadata for retrieval systems requires careful consideration of data recoverability and query performance. Fields should be categorized based on whether they are unrecoverable after ingestion, expensive to recompute (e.g., model-generated summaries), or cheap to recompute. It is crucial to store unrecoverable fields, such as the source of data or parser version, as they cannot be obtained later. For query efficiency, filtering fields like language or tenant ID should be directly associated with the data chunk rather than requiring a join to a separate document table. AI
