Retrieve

Source: src/AWS/Kendra/Retrieve.ts

Runtime binding for the Retrieve operation (IAM action kendra:Retrieve), scoped to one Index.

Retrieves up to 100 semantically-relevant passages (200-token excerpts) from the index — the building block for retrieval-augmented generation (RAG) over documents synced into Kendra. Provide the implementation with Effect.provide(AWS.Kendra.RetrieveHttp).

Querying an Index

const retrieve = yield* AWS.Kendra.Retrieve(index);

const passages = yield* retrieve({ QueryText: "vacation policy" });
const context = (passages.ResultItems ?? [])
  .map((item) => item.Content)
  .join("\n");
