# RerankingMetadataSelectiveModeConfiguration
<a name="API_agent-runtime_RerankingMetadataSelectiveModeConfiguration"></a>

Contains configurations for the metadata fields to include or exclude when considering reranking. If you include the `fieldsToExclude` field, the reranker ignores all the metadata fields that you specify. If you include the `fieldsToInclude` field, the reranker uses only the metadata fields that you specify and ignores all others. You can include only one of these fields.
