如何计算今天的日期和文档中的日期之间的天差，但在弹性搜索脚本中从中消除时间

Question

I tried this solution and it works but it takes time stamp also....I want to eliminate time stamp...

"filter": {
    "script": {
        "script": { 
            "inline":"(new Date().getTime() - doc['current_edd'].date.getMillis()) /
                            (1000 * 60 * 60 * 24)  == params.missDelby",
             "params": { "missDelby": 1 }
         }
     }
 }

Answer 1

Use can use some math to remove the time part with this simple calcul

long t1 = new Date().getTime();
t1 -= t1 % (24 * 3600 * 1000); //24 * 3600 * 1000 total milliseconds in a day

The you can update your query like this

"filter": {
    "script": {
        "script": { 
            "inline": "long t1 = new Date().getTime(); 
                       long t2 = doc['PostCodeDate'].value.getMillis(); 
                       t1 -= t1 % (24 * 3600 * 1000); 
                       t2 -= t2 % (24 * 3600 * 1000);
                       return (t1 - t2) / (24 * 3600 * 1000) == params.missDelby",
             "params": { "missDelby": 1 }
         }
     }
}

I'll update my solution as soon as I found a simpler approach.
