# Create a field setting for an AI Search indexed source

Define an indexed source field setting to configure AI Search content indexing behavior for a specific field on source table records.

## Before you begin

## About this task

For details on available field settings and values, see [List of AI Search indexed source field settings](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-administration/ai-search/field-settings-list-ais.md).

## Procedure

1.  Navigate to **All** > **AI Search** > **AI Search Index** > **Indexed Sources**.

2.  Open the indexed source that you want to define a field setting for.

3.  In the Field Settings & Mapping related list, select **New**.

4.  On [the Field Setting form](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-administration/ai-search/field-setting-form-ais.md), fill in the fields.

5.  Select **Submit**.


## Result

## What to do next

To make the new field setting take effect, perform a full table reindex for the indexed source.
