Prevent AI Search from indexing content found in your knowledge blocks.

## Before you begin

Role required: admin

## About this task

Starting in Xanadu Patch 3, AI Search includes content specified in your published knowledge blocks when it indexes content and metadata from your knowledge articles.

Administrators can override this default behavior and exclude your knowledge block content from the search index by setting the value of the glide.ais.disable_kbb system property. If this system
property's value is set to true, AI Search ignores knowledge block content when indexing content and metadata from your knowledge articles.

To learn more about creating and publishing knowledge blocks for reference in your knowledge articles, see [Using knowledge blocks](https://www.servicenow.com/docs/access?context=using-knowlege-blocks&version=xanadu&pubname=xanadu-servicenow-platform&ft:locale=en-US).

## Procedure

1. Navigate to the System Property \[sys_properties\] table's list view.
   1. Select All.
   2. In the Filter field, enter <kbd class="ph userinput">sys_properties.list</kbd>.
   3. Press Enter.
   {#exclude-know-blocks-ais-index__substeps_hny_2t5_b1c}
2. Search for a system property record with name glide.ais.disable_kbb.
   * If a system property record with this name exists, open the record by selecting it.
   * If no system property record with this name exists, select New, then enter <kbd class="ph userinput">glide.ais.disable_kbb</kbd> in the System Property form's Name field.
   {#exclude-know-blocks-ais-index__choices_d2q_zw5_b1c}
3. In the System Property form's Value field, enter true.
4. Save the modified System Property record by selecting Submit or Update.

## What to do next

To make the new setting take effect, reindex the Knowledge Table indexed source. For details on reindexing, see [Perform a full table index or reindex for a single AI Search indexed source](https://servicenow-prod.fluidtopics.net/ylmJp1OFiNmWvOFFxmjvuw "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.").
