Query Feature using OpenLayers + MapServer

I'm trying to query a feature in OpenLayers, but it's returning just an image highlighted that is not possible to make zoom, pan and drag.

My intention is to query a feature on the map like street name, city and country. Is there any function in OpenLayers?

I'm using this code:

var query = new OpenLayers.Layer.WMS( "Utbs", 
    "http://localhost/cgi-bin/wms.exe", 

    {
    srs: 'EPSG:4326',
    width: '800',
    styles: '',
    height: '600',
    layers: 'layer_name',   
    mode: 'itemquerymap',
    qstring: "(value = '03')",
    qlayer: 'layer_name',
    mapxy: 'shape'  

    },
    {
    singleTile: true    
    }
);

map.addLayers([utbs_query]);
map.zoomToMaxExtent();
