Does AI Search OOTB index the content of all file types attached to our knowledge articles?

Can I check a property somewhere which states what file types are being indexed?

Hello @Johan van den H 

You can check the property that defines which file types are indexed by AI Search:

Navigate to AI Search Configuration

Go to System Properties → AI Search
Look for properties related to file attachment indexing.
Check (glide.aisearch.index.attachments) Property

This property determines if attachments are indexed.
If enabled (true), only supported file types are indexed.

Review the Supported File Types in Documentation

File types like .pdf, .docx, .txt may be indexed if AI Search supports content extraction for those formats.
You can verify this in ServiceNow’s official documentation or by testing with sample attachments.

Use the sys_attachment Table to Review Indexed Attachments

Query the sys_attachment table to check which attachments are processed.

Thank you for responding to my question @rohansargar .

Navigate to AI Search Configuration

Go to System Properties → AI Search
Look for properties related to file attachment indexing.

I do not see any AI Search properties related to file attachment indexing here.

Check (glide.aisearch.index.attachments) Property

This property determines if attachments are indexed.
If enabled (true), only supported file types are indexed.

Also this property is not available in our instance.

In the Xanadu documentation I found an article named "Indexed source attributes" which contained the following info which is the answer to my question:

By default, AI Search indexes searchable content and metadata (such as file size and date) for attachments found on source table records. Indexing supports the following attachment file formats:

• Active Server Page Extended (.aspx)
• Hypertext Markup Language (.html, .htm)
• Microsoft Excel (.xls, .xlsx)
• Microsoft PowerPoint (.pot, .potx, .ppt, .pptm, .pptx)
• Microsoft Word (.doc, .docx, .dot, .dotx)
• Plain Text (.txt)
• Portable Document Format (.pdf)
