# DocumentAttributeBoostingConfiguration
<a name="API_DocumentAttributeBoostingConfiguration"></a>

Provides information on boosting supported Amazon Q Business document attribute types. When an end user chat query matches document attributes that have been boosted, Amazon Q Business prioritizes generating responses from content that matches the boosted document attributes.

In version 2, boosting uses numeric values (ONE, TWO) to indicate priority tiers that establish clear hierarchical relationships between boosted attributes. This allows for more precise control over how different attributes influence search results.

**Note**  
For `STRING` and `STRING_LIST` type document attributes to be used for boosting on the console and the API, they must be enabled for search using the [DocumentAttributeConfiguration](https://docs.aws.amazon.com/amazonq/latest/api-reference/API_DocumentAttributeConfiguration.html) object of the [UpdateIndex](https://docs.aws.amazon.com/amazonq/latest/api-reference/API_UpdateIndex.html) API. If you haven't enabled searching on these attributes, you can't boost attributes of these data types on either the console or the API.

For more information on how boosting document attributes work in Amazon Q Business, see [Boosting using document attributes](https://docs.aws.amazon.com/amazonq/latest/business-use-dg/metadata-boosting.html).
