# List of AI Search Datasource Churn Audit fields

Field descriptions for the AI Search Datasource Churn Audit table, which lists fields that AI Search has flagged as high-churn.

For steps on using this data to make an indexing decision, see [Review high-churn field audit results](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-administration/ai-search/review-churn-audit-results-ais.md).

The lower of the **Field Type Score** band and the **Frequency Score** band.**Churn Score** is automatically set to **Blocked** if Safety Guard detects that any ACL, search source, or result improvement rule depends on the field. This setting overrides the band derived from **Field Type Score** and **Frequency Score**. For details, see [High-churn field detection](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-administration/ai-search/high-churn-field-detection-ais.md).
