+        * `"network-only"`: *(default)* Always issue a network request, regardless of what is in the store.
+        * `"store-or-network"`: Reuse data from the store if the full query is available locally; otherwise, issue a network request.
+
+        The `"store-and-network"` and `"store-only"` fetch policies are **not supported** by `fetchQuery`, because it is designed around issuing a single network request and returning the response. If you need those policies, use [`useLazyLoadQuery`](../use-lazy-load-query/) instead.
