function osas(){`enter code here`     client.deletebyquery({       index: 'lostit',       type: 'string',       body: {        "query": {        "range" : {        "date" : {         "lte": "now-5d"                 }                }             }            }      }, function(err, res) {      if (err) {         console.error(err.message);     } else {         console.log('indexes have been deleted!');     } });     }    osas();
