A new system called AnnoIndex has been developed to improve querying of unstructured documents. It addresses limitations in current retrieval methods by first creating a structured index from text using a process called SchemaLoop, which extracts and organizes information. This structured index allows for precise filtering and querying, with a query engine that compiles questions into SQL extensions. The system prioritizes using the structured index for filtering before resorting to large language models for deep semantic understanding, significantly outperforming existing baselines in experiments.
