Lexical Retrieval

Created Updated openspec/changes/define-hybrid-retrieval/specs/lexical-retrieval/spec.mdView on GitHub →

MODIFIED Requirements

Requirement: The extension SHALL expose GET /v1/search with a constrained query surface

GET /v1/search SHALL remain the lexical retrieval endpoint even when a server also advertises hybrid retrieval. Hybrid retrieval SHALL NOT silently alter lexical result ranking, filtering, scoring, or response shape.

Scenario: Hybrid retrieval is also available

  • WHEN a server advertises both lexical retrieval and hybrid retrieval
  • THEN GET /v1/search SHALL continue to behave as lexical retrieval
  • AND clients that want blended recall SHALL call the advertised hybrid endpoint.
