Question

嗨这是弹性搜索的样本输出

"table":{  
   "data":[  
      {  
         "label":"First Label",
         "value":"10"
      },
      {  
         "label":"1st Label",
         "value":"9"
      }
   ],
   "details":"Examples set on MSRP, your actual payment may vary based on price set by dealer."
}

我希望按升序排序，无论是通过colunm标签还是通过值。

我尝试的搜索选项是

sort = [{"data.label" : {"order" : "asc", "mode" : "min", "nested_path" : "data"}}];
sort = [{ "table.data": {"order": "asc"}]

但是，我没有得到预期的排序结果

对此的任何帮助将不胜感激

Answer 1

查询的排序部分应为 -

"sort": { "label":   { "order": "desc" }}

或

"sort": { "value":   { "order": "desc" }}

或

"sort": [
        { "label":   { "order": "desc" }},
        { "value": { "order": "desc" }}
    ]

以下是获取内部排序元素的映射，文档和后续查询。

PUT /table
{
  "mappings": {
    "data": {
      "properties": {
        "name": {"type": "string"},
        "subjects": {
          "type": "nested", 
          "properties": {
            "name": { "type": "string"},
            "marks":{ "type": "integer"}
          }
        }
      }
    }
  }
}

PUT /table/data/1?pretty 
{
  "name":"Ram",
  "subjects":[
    { 
      "name":"English",
      "marks":13
    },
    { 
      "name":"Hindi",
      "marks":12
    }
    ]
}
PUT /table/data/2?pretty 
{
  "name":"Sam",
  "subjects":[
    { 
      "name":"Biology",
      "marks":83
    },
    { 
      "name":"Maths",
      "marks":68
    }
    ]
}

PUT /table/data/3?pretty 
{
  "name":"Jim",
  "subjects":[
    { 
      "name":"Chemistry",
      "marks":96
    },
    { 
      "name":"Geology",
      "marks":58
    }
    ]
}

GET table/data/_search
{
 "query":{
   "nested":{
     "path":"subjects",
     "query": {
        "match_all": {}
      },
     "inner_hits":{
       "sort":{
         "subjects.marks":{
           "order":"asc"
         }
       }
     }
   }
 }
}

弹性搜索排序不起作用
