retrieve-and-generate

Description

Queries a knowledge base and generates responses based on the retrieved results and using the specified foundation model or inference profile . The response only cites sources that are relevant to the query.

See also: AWS API Documentation

retrieve-and-generate uses document type values. Document types follow the JSON data model where valid values are: strings, numbers, booleans, null, arrays, and objects. For command input, options and nested parameters that are labeled with the type document must be provided as JSON. Shorthand syntax does not support document types.

If you’re using an Amazon OpenSearch Serverless vector store that contains a filterable text field, you can specify whether to query the knowledge base with a HYBRID search using both vector embeddings and raw text, or SEMANTIC search using only vector embeddings. For other vector store configurations, only SEMANTIC search is available. For more information, see Test a knowledge base .

rerankingConfiguration -> (structure)

Contains configurations for reranking the retrieved results. For more information, see Improve the relevance of query responses with a reranker model .

bedrockRerankingConfiguration -> (structure)

Contains configurations for an Amazon Bedrock reranker model.

metadataConfiguration -> (structure)

Contains configurations for the metadata to use in reranking.

selectionMode -> (string)

Specifies whether to consider all metadata when reranking, or only the metadata that you select. If you specify SELECTIVE , include the selectiveModeConfiguration field.

selectiveModeConfiguration -> (tagged union structure)

Contains configurations for the metadata fields to include or exclude when considering reranking.

Note

This is a Tagged Union structure. Only one of the following top level keys can be set: fieldsToExclude, fieldsToInclude.

fieldsToExclude -> (list)

An array of objects, each of which specifies a metadata field to exclude from consideration when reranking.

(structure)

Contains information for a metadata field to include in or exclude from consideration when reranking.

fieldName -> (string)

The name of a metadata field to include in or exclude from consideration when reranking.

fieldsToInclude -> (list)

An array of objects, each of which specifies a metadata field to include in consideration when reranking. The remaining metadata fields are ignored.

(structure)

Contains information for a metadata field to include in or exclude from consideration when reranking.

fieldName -> (string)

The name of a metadata field to include in or exclude from consideration when reranking.

modelConfiguration -> (structure)

Contains configurations for the reranker model.

additionalModelRequestFields -> (map)

A JSON object whose keys are request fields for the model and whose values are values for those fields.

key -> (string)

value -> (document)

modelArn -> (string)

The ARN of the reranker model to use.

numberOfRerankedResults -> (integer)

The number of results to return after reranking.

type -> (string)

The type of reranker model.

type -> (string)

The type of resource that contains your data for retrieving information and generating responses.

If you choose ot use EXTERNAL_SOURCES , then currently only Claude 3 Sonnet models for knowledge bases are supported.

--session-configuration (structure)

Contains details about the session with the knowledge base.

kmsKeyArn -> (string)

The ARN of the KMS key encrypting the session.

Shorthand Syntax:

kmsKeyArn=string

JSON Syntax:

{
  "kmsKeyArn": "string"
}

--session-id (string)

The unique identifier of the session. When you first make a RetrieveAndGenerate request, Amazon Bedrock automatically generates this value. You must reuse this value for all subsequent requests in the same conversational session. This value allows Amazon Bedrock to maintain context and knowledge from previous interactions. You can’t explicitly set the sessionId yourself.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

• json
• text
• table
• yaml
• yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

• on
• off
• auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

• base64
• raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.
