In the ESRI example they use an infoWindow. You can just add it like this:
geocoder.on("select", showLocation);
function showLocation(evt) {
map.graphics.clear();
var point = evt.result.feature.geometry;
var symbol = new SimpleMarkerSymbol().setStyle(
SimpleMarkerSymbol.STYLE_SQUARE).setColor(
new Color([255,0,0,0.5])
);
var graphic = new Graphic(point, symbol);
map.graphics.add(graphic);
map.infoWindow.setTitle("Search Result");
map.infoWindow.setContent(geocoder.results[0].feature.attributes.score+",<br><h3>Some other Fields</h3>");
map.infoWindow.show(evt.result.feature.geometry);
}
Here is the full code of an exmaple modified from esri
