rerank

Description

Reranks the relevance of sources based on queries. For more information, see Improve the relevance of query responses with a reranker model .

See also: AWS API Documentation

rerank 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.

rerank is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: results

    "type": "TEXT"
  }
  ...
]

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.

numberOfResults -> (integer)

The number of results to return after reranking.

type -> (string)

The type of reranker that the configurations apply to.

Shorthand Syntax:

bedrockRerankingConfiguration={modelConfiguration={modelArn=string},numberOfResults=integer},type=string

JSON Syntax:

{
  "bedrockRerankingConfiguration": {
    "modelConfiguration": {
      "additionalModelRequestFields": {"string": {...}
        ...},
      "modelArn": "string"
    },
    "numberOfResults": integer
  },
  "type": "BEDROCK_RERANKING_MODEL"
}

--sources (list)

An array of objects, each of which contains information about the sources to rerank.

(structure)

Contains information about a source for reranking.

inlineDocumentSource -> (structure)

Contains an inline definition of a source for reranking.

jsonDocument -> (document)

Contains a JSON document to rerank.

textDocument -> (structure)

Contains information about a text document to rerank.

text -> (string)

The text of the document.

type -> (string)

The type of document to rerank.

type -> (string)

The type of the source.

Shorthand Syntax:

inlineDocumentSource={textDocument={text=string},type=string},type=string ...

      "type": "TEXT"|"JSON"
    },
    "type": "INLINE"
  }
  ...
]

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

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

--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.

Output

If the total number of results is greater than can fit in the response, use this token in the nextToken field when making another request to return the next batch of results.
