## Index external sitemaps in search

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.
