To validate DSL requests, you can enforce a restricted server contract that maps allowed query shapes to a deterministic OpenSearch format, preventing unsafe inputs from reaching the execution layer.

Exposing API schema and query limits is achieved through a dedicated schema endpoint, which defines allowed fields, aggregations, and hard limits for clients interacting with the custom DSL.

Standardizing API responses involves wrapping query results in a standardized ApiEnvelope, while the server contract handles request auditing to ensure consistent error reporting and execution tracking.

Yes, you can restrict allowed aggregations and fields by applying a deterministic DSL validation layer that enforces hard limits and blocks unauthorized query shapes before they execute.

A deterministic server contract is needed to ensure only allowed DSL query shapes are executed against OpenSearch, mitigating the risk of unsafe inputs and guaranteeing consistent response envelopes.
