        <script>

          var map = new ol.Map({

            layers: [
              new ol.layer.Tile({
                source: new ol.source.OSM()
              })
            ],
            target: 'map',
            view: new ol.View({
              center: ol.proj.fromLonLat([51.39, 35.70]),
              zoom: 13
            })
          });
        </script>

Solution

  • If you're looking for controls to let the user search places on your map, have a look at this example with Nominatim or this with Photon API. Just create a control and add it to the map. Then do something when a place is selected (center the map): 

    // Set the search control 
var search = new ol.control.SearchNominatim ({
// or: = new ol.control.SearchPhoton({
  lan: 'en',
  position: true    // Search, with priority to geo position
});
map.addControl (search);

// Center map when destination is selected
search.on('select', function(e) {
  map.getView().animate({
    center: e.coordinate,
    zoom: Math.max (map.getView().getZoom(),16)
});

    If you want to geocode a bulk of addresses, look at API used by the example and their implementation in the lib.
