# AWS::Bedrock::FlowVersion LoopFlowNodeConfiguration
<a name="aws-properties-bedrock-flowversion-loopflownodeconfiguration"></a>

Contains configurations for the nodes of a DoWhile loop in your flow.

A DoWhile loop is made up of the following nodes:
+ `Loop` - The container node that holds the loop's flow definition. This node encompasses the entire loop structure.
+ `LoopInput` - The entry point node for the loop. This node receives inputs from nodes outside the loop and from previous loop iterations.
+ Body nodes - The processing nodes that execute within each loop iteration. These can be nodes for handling data in your flow, such as a prompt or Lambda function nodes. Some node types aren't supported inside a DoWhile loop body. For more information, see [LoopIncompatibleNodeTypeFlowValidationDetails](https://docs.aws.amazon.com/bedrock/latest/APIReference/API_agent_LoopIncompatibleNodeTypeFlowValidationDetails.html).
+ `LoopController` - The node that evaluates whether the loop should continue or exit based on a condition.

These nodes work together to create a loop that runs at least once and continues until a specified condition is met or a maximum number of iterations is reached.

`AdditionalModelRequestFields`  <a name="cfn-bedrock-flowversion-vectorsearchbedrockrerankingmodelconfiguration-additionalmodelrequestfields"></a>
A list of additional fields to include in the model request during reranking. These fields provide extra context or configuration options specific to the selected foundation model.  
*Required*: No  
*Type*: Json  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`ModelArn`  <a name="cfn-bedrock-flowversion-vectorsearchbedrockrerankingmodelconfiguration-modelarn"></a>
The Amazon Resource Name (ARN) of the foundation model to use for reranking. This model processes the query and search results to determine a more relevant ordering.  
*Required*: Yes  
*Type*: String

# AWS::Bedrock::FlowVersion VectorSearchRerankingConfiguration
<a name="aws-properties-bedrock-flowversion-vectorsearchrerankingconfiguration"></a>

Configuration for reranking vector search results to improve relevance. Reranking applies additional relevance models to reorder the initial vector search results based on more sophisticated criteria.

## Syntax
<a name="aws-properties-bedrock-flowversion-vectorsearchrerankingconfiguration-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON

`BedrockRerankingConfiguration`  <a name="cfn-bedrock-flowversion-vectorsearchrerankingconfiguration-bedrockrerankingconfiguration"></a>
Configuration for using Amazon Bedrock foundation models to rerank search results. This is required when the reranking type is set to BEDROCK.  
*Required*: No  
*Type*: [VectorSearchBedrockRerankingConfiguration](aws-properties-bedrock-flowversion-vectorsearchbedrockrerankingconfiguration.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Type`  <a name="cfn-bedrock-flowversion-vectorsearchrerankingconfiguration-type"></a>
The type of reranking to apply to vector search results. Currently, the only supported value is BEDROCK, which uses Amazon Bedrock foundation models for reranking.  
*Required*: Yes  
*Type*: String  
*Allowed values*: `BEDROCK_RERANKING_MODEL`
