mysql - 相当于此mysql查询 "delete from item_img where datediff(now(), date) > 5"的Elastic搜索deletebyquery

Question

请搜索与此 mysql 查询“delete from item_img where datediff(now(), date) > 5”等效的 Elastic search deleteByQuery

这是我的代码，但它不起作用

function osas(){`enter code here`


  client.deleteByQuery({
      index: 'lostit',
      type: 'string',
      body: {
       "query": {
       "range" : {
       "date" : {
        "gt": "now+20m"
                }
               }
            }

          }
     }, function(err, res) {

    if (err) {
        console.error(err.message);
    } else {
        console.log('Indexes have been deleted!');
    }
});
    }
   osas();

//它是基于nodejs连接器到elasticsearch编写的

无论如何，我想我已经弄清楚了......使用数学中不等式方程的概念

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();
