Retriever

Source: src/AWS/QBusiness/Retriever.ts

An Amazon Q Business retriever — the query engine that fetches relevant passages from an index (native or Kendra) to ground chat responses.

Creating Retrievers

Native Index Retriever

import * as AWS from "alchemy/AWS";

const retriever = yield* AWS.QBusiness.Retriever("Docs", {
  applicationId: app.applicationId,
  type: "NATIVE_INDEX",
  configuration: {
    nativeIndexConfiguration: { indexId: index.indexId },
  },
});

Kendra Index Retriever

const retriever = yield* AWS.QBusiness.Retriever("Kendra", {
  applicationId: app.applicationId,
  type: "KENDRA_INDEX",
  roleArn: role.roleArn,
  configuration: {
    kendraIndexConfiguration: { indexId: kendraIndex.id },
  },
});
