try{
var referenceresultado= this.resultadoref.orderByChild(‘Producto’).equalTo(this.resultado);
referenceresultado.on(‘value’, itemSnapshot => {
this.products = [];
itemSnapshot.forEach( itemSnap => {
this.products.push(itemSnap.val());

 let alert = this.alertCtrl.create({
title: 'Producto encontrado! :D',

});
alert.present();

  return false;
});

});

}catch(Error){
