# Review churn audit results

# Review high-churn field audit results {#ariaid-title1}

Release version: Brazil  
Updated September 17, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 2 minutes to read  
Review fields that AI Search flagged as high-churn and decide whether to keep indexing them or exclude them from the index.

## Before you begin

Role required: admin

## About this task

AI Search audits fields from indexed tables. If a field is frequently updated, an audit record for it appears in the AI Search Datasource Churn Audit \[ais_datasource_churn_audit\] table. Administrators can review a field's audit record and decide whether to keep indexing the field or to exclude it from future indexing
operations.

For background on how high-churn fields are detected and scored, see [High-churn field detection](https://www.servicenow.com/docs/1816VXgwvCPBpmnjZvhS1A "Some indexed source fields change so frequently that repeatedly reindexing them adds load to AI Search without adding search value. AI Search automatically identifies these high-churn fields and lets an admin decide whether to continue indexing them or to exclude them from the index going forward.").

## Procedure

1. Navigate to the AI Search Datasource Churn Audit \[ais_datasource_churn_audit\] table's list view.
   1. Select All.
   2. In the navigation field, enter <kbd class="ph userinput">ais_datasource_churn_audit.list</kbd>.
   3. Press Enter.
   {#review-churn-audit-results-ais__substeps_htg_ff5_b1c}
2. Select a field audit record with an Admin Decision value of Pending.
3. To understand why the field was flagged as high-churn, review the record's Churn Score, Frequency Score, Field Type Score, and Detection Note.  
   For field descriptions, see [List of AI Search Datasource Churn Audit fields](https://www.servicenow.com/docs/VkX9vHg22gA3XE3v2Oiq0w "Field descriptions for the AI Search Datasource Churn Audit table, which lists fields that AI Search has flagged as high-churn.").
4. Set the Admin Decision field value for the audit record.
   * If the audit record's Churn Score is Blocked, leave the Admin Decision as Pending.  
     Note:  
     A blocked field can't be excluded from indexing because the Safety Guard dependency check found at least one ACL, search source filter, or result improvement rule that depends on it being present in the index.
   * Otherwise, set the audit record's Admin Decision field value to Exclude From Indexing or Continue Indexing.  
     Note:  
     To undo a previous exclusion decision, you can change an audit record's Admin Decision field value from Exclude From Indexing to Continue Indexing. You can't set this field back to Pending, however.

     The Safety Guard dependency check can't detect when a field is referenced in a scripted ACL or a Before Query business rule. If either of these conditions is true for a field, don't
     exclude that field from indexing.
5. Select Update.

## Result

Future indexing operations exclude fields that you set to Exclude From Indexing.

Fields that you set to Exclude From Indexing or Continue Indexing aren't re-scored in churn audits from future indexing operations.

## What to do next

If you set any field's Admin Decision to Exclude From Indexing, that field will remain in the index until the source table is reindexed. For details on reindexing content, see [Perform a full table index or reindex for a single AI Search indexed source](https://www.servicenow.com/docs/aJr1jGJnO2CNPYFYvxitWw "Make content from an internal indexed source searchable by performing a full table index. This procedure indexes existing records from the source table and any child tables configured for indexing. You can manually reindex content from an internal indexed source by repeating this procedure.") and [Perform a full table index or reindex for multiple AI Search indexed sources](https://www.servicenow.com/docs/gE4JGiHBUx~tyw3Q8K~UmA "Make content from multiple internal indexed sources searchable by performing a full table index. This procedure indexes existing records from the source tables and any child tables configured for indexing. You can manually reindex content from internal indexed sources by repeating this procedure.").
