This is leaflet plugin for photon.

Use the map options to create a Photon search control when the map is created:

function myHandler(geojson) {
    console.debug(geojson);
};
var map = L.map('map', {
  photonControl: true,
  photonControlOptions: {
      resultsHandler: myHandler,
      placeholder: 'Try me …',
      position: 'topleft'}
  }
);

Or create a control afterwards:

var searchControl = L.control.photon(photonControlOptions);
searchControl.addTo(map);
