Search location using geocode API in google maps

I would like to acheive the exact same result rendered from a google maps url "http://maps.google.co.in/maps?q=canara+bank&hl=en&sll=12.953997,77.63094&sspn=1.069318,1.234589&hq=canara+bank&t=m&z=10" using the google maps API.

I've tried using the geoCode API, but some have been unable to achieve a similar result.

    geocoder.geocode( {

        var longitude = results[0].geometry.location.lng();

            };
           var map = new google.maps.Map(document.getElementById("map_canvas"),
            mapOptions);


     var marker = new google.maps.Marker({    
             position: new google.maps.LatLng(results[0].geometry.location.lat(), results[0].geometry.location.lng()),    
             map: map    
            });

//for placing the markers
    var markers;
    var i;      
    for(i=0;i<results.length;i++){
        markers = new google.maps.Marker({    
            position: new google.maps.LatLng(results[i].geometry.location.lat(), results[i].geometry.location.lng()),    
            map: map,
           });
     }

     var circleOptions = new google.maps.Circle({
                  center: new google.maps.LatLng(latitude, longitude),
                  radius: 2000,
                  strokeColor: "#FF0000",
                  strokeOpacity: 0.5,
                  strokeWeight: 2,
                  fillColor: "#FF0000",
                  fillOpacity: 0.35,
                  map: map
                });       

    }
} );

}

</script>

</head>
<body onload="getLocation()">

<div id="map_canvas" style="width: 100%; height: 50%"></div>
<form name="form_simple" action=" " method="get">
    <center>
        <label id="d1"> map test</label>
    </center>
</form>

I would also like to know if there is an sll(parameter in the google maps to specify lat and lng ) alternative while using the geocode API.

Thanks in advance.

"Canara Bank" is not an address. The geocoding API converts addresses to coordinates (from the documentation):

Geocoding is the process of converting addresses (like "1600 Amphitheatre Parkway, Mountain View, CA") into geographic coordinates (like latitude 37.423021 and longitude -122.083739)

You want the Places API:

The Google Places API is a service that returns information about Places — defined within this API as establishments, geographic locations, or prominent points of interest
