+  ## Searchable hidden tabs and groups
+
+  Setting `searchable: true` on a hidden tab or group in `docs.json` now exposes its descendant pages across every discovery surface, while keeping the tab or group hidden from the rendered navigation. Descendants are included in:
+
+  - Documentation site search
+  - `sitemap.xml`
+  - `llms.txt`
+  - Assistant context and MCP server search results
+  - Search engine indexing — the `<meta name="robots" content="noindex">` tag is no longer emitted for opted-in pages
+
+  ```json highlight={4-5}
+  "tabs": [
+    {
+      "tab": "Storage",
+      "hidden": true,
+      "searchable": true,
+      "groups": [
+        {
+          "group": "Buckets",
+          "pages": ["products/storage/buckets/create-bucket"]
+        }
+      ]
+    }
+  ]
+  ```
+
+  See [Hidden pages](/organize/hidden-pages#include-pages-under-specific-hidden-tabs-or-groups) for details.
