node["emergency"="defibrillator"](user:"<username>")({{bbox}});
out;

Display ways

As point

way["amenity"="restaurant"]({{bbox}});
out center;

As area

way["amenity"="restaurant"]({{bbox}});
(._;>;);
out;

Union of nodes and ways as point

[bbox:{{bbox}}];
(
  node["amenity"="restaurant"];
  way["amenity"="restaurant"];
);
out center;

Multiple queries

Combination of values

node["amenity"~"restaurant|bar"]({{bbox}});
