Definition
A retrieval technique where natural language queries are mapped to structured query languages (like SQL or Cypher) or metadata filters to extract data from formatted sources. It prioritizes precision and hard constraints over the fuzzy similarity matches typical of pure vector-based retrieval.
Schema-aware querying of databases versus vector-similarity querying of unstructured text.
