I'm trying to integrate the geocoder of Google Maps into my ol-map. There are a lot of similar questions asked. I tried out this: http://dev.openlayers.org/sandbox/topp/almanac/examples/geocoder.html example but it doesn't work. Looking through: How to use Google Maps geocoding with Openlayers? also didn't help me.

(As I'm new here I cannot comment on peoples answers so I thought it might be OK to open a new question - tell me if I'm wrong) See code below for my attempt. Do you have any tips or know any working example?

Maybe your search() function should look like this:

    function search(){
    var address = document.getElementById('address').value+",Kathmandu, Nepal";

    geocoder.geocode( { 'address': address}, function(results, status) {
          if (status == google.maps.GeocoderStatus.OK) {
            var loc = new OpenLayers.LonLat(results[0].geometry.location.lat(), results[0].geometry.location.lng())
            map.setCenter(loc, 3);

          } else {
            alert("Geocode was not successful for the following reason: " + status);
          }
    });
}

Other than this, in your example you seemed to have mixed the deprecated google maps api v2 code with the openlayers code.
