Hello, we've noticed that knowledge block attachments (kb_knowledge_block) do not appear to be indexed with AI Search. We can't add the kb_knowledge_block table as a child table on the AI Search Indexed Source for Knowledge table (kb_knowledge), either -- an alert message appears, "Invalid update - kb_knowledge_block cannot be added as a child table." Has anyone else experienced this issue, or have any thoughts about a workaround?

Hi @Zach3, that block is real: kb_knowledge_block isn't accepted as a child table on an AI Search Indexed Source, and there's no published fix or workaround for it. Practically, that means attachments never get evaluated at all, because attachment indexing (the index_attachments attribute under Advanced Configuration on the Indexed Source) only ever applies at the source table or one of its configured child tables, and kb_knowledge_block can't hold either role. Until ServiceNow opens that up, move anything that needs to be AI Search-able onto the parent kb_knowledge record instead of the block, since kb_knowledge is a fully supported source. Worth logging a HI case too: this reads like a product gap, not a config you're missing.
