External sitemaps indexed in Docs search

Index external sitemaps in search

You can now surface pages hosted outside your docs site in search. List one or more external sitemap.xml files under the experimental external-sitemaps key in docs.yml, and Fern indexes their pages into the same search index as your documentation. External results are flagged as third-party, so they always rank below your first-party pages and open in a new tab when selected.
