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/australia/markdown/australia/platform-administration/ai-search/review-churn-audit-results-ais.md).
