过滤

需求: 如果aaa字段不存在,则使用bbb字段
aaa<=结果<=bbbb

java代码

Script script =new Script("if(doc['qc_review_score'].empty==true){" +
              "if(doc['qc_score'].value<="+getScoreMax()+"){" +

//创建scriptquery
ScriptQueryBuilder filterBuilder = QueryBuilders.scriptQuery(script);
parentQuery.filter(filterBuilder);

排序

      "_script": {
        "script": {

        "type": "number", 
        "order": "asc"
      }
    }, 
    {
      "unique_id": {
        "order": "desc"
      }
    }
  ], 
  "ext": { }
}

java代码

Script script = new Script("doc['qc_review_score'].empty==true? doc['qc_score'].value:doc['qc_review_score'].value");
sortBuilder = SortBuilders.scriptSort(script,ScriptSortBuilder.ScriptSortType.NUMBER).order(orderType==0?SortOrder.ASC:SortOrder.DESC);
searchSourceBuilder.sort(sortBuilder);
