# Notion API Content queries to notion-search can route to AI search

Markdown version of <https://harbyn.com/changes/notion/2026-09-10-ai-search-accepts-filters-and-notion-search-routes-content-queries-to-it-2>.

Behavior change - Notion API. low severity. In effect.

When notion-fetch with the id self reports current\_tool\_access.ai\_search.status as available, keyword content queries sent to notion-search search Notion and connected sources and report type: "ai\_search". Calls with an exact filter, an empty query, or a sort other than relevance stay on Notion workspace search. Connections that cannot use notion-ai-search keep content searches on workspace search; the legacy content\_search\_mode: "ai\_search" parameter returns a permission error for those connections. User lookup with query\_type: "user" remains on notion-search.
