查询弹性搜索JSON

问题描述

我的数据从平面文件进入logstash我试图查询弹性搜索。

  OrderNumber ProductName 
 order1 Chicken 
 order2香蕉
 order3 Chicken 
 order1黄瓜
订单2鸡
订单3苹果
订单1面粉
订单2米
订单3坚果
  

如上所述，我有一个鸡< 的产品名称，发生在不同的订单号。

  OrderNumber ProductName 
 order1 Chicken 
 order3 Chicken 
 order2 Chicken 
  

这是我想要实现的：

步骤1：查找包含鸡的所有订单号

  OrderNu mber ProductName 
 order1 Chicken 
 order3 Chicken 
 order2 Chicken 
  

步骤2：如果上面的订单有鸡，它给我所有其他也被购买的产品

结果：

  OrderNumber ProductName 
 order1黄瓜
 order2香蕉
 order3苹果
 order1面粉
 order2 Rice 
 order3坚果
  

这是我迄今为止尝试过的 Step1

查询

  {
query：{
match：{
ProductName：Chicken
} 
} 
} 
  

结果

 hits：{
total：3，
max_score：11.378191，
hits：[{ 
_index：hello，
_type：logs，
_id：AVmxaChupyZuCjD89xPX，
_score：11.378191，
 _source：{
message：order1\Chicken\r，
path：C：\\utils\\\Elk\\loglog \\\bin\\product.log，
OrderNumber：order1，
ProductName：Chicken\r
}}，{
_index：hello，
_type：logs，
_id：AVmxaChupyZuCjD89xPX，
_score：11.378191，
_source ：{
message：order3\Chicken\r，
path：C：\\utils\\Elk\\logstash\\\\ bin \\product.log，
OrderNumber：order3，
ProductName：Chicken\r
} 
}，{
_index：hello，
_type：logs，
_id：AVmxaChupyZuCjD89xPX，
_sco re：11.378191，
_source：{
message：order2\Chicken\r，
path：C：\\utils\ \Elk\\logstash\\bin\\product.log，
OrderNumber：order2，
ProductName：Chicken\r
} 
  

我非常困惑，如何完成步骤2 ，因为我非常新的Elasticsearch，请帮助？

谢谢

解决方案

要搜索具有 Chicken 和 Chicken 之外的产品名称的文档，您可以使用以下查询：

  {
查询：{
和：[
 {
条款：{
OrderNumber：[order1，order2，order3] 
} 
}，
 { 
not：{
term：{
Pr oductName：鸡
} 
} 
} 
] 
} 
} 
  

I am trying to query elasticsearch in order to find out what products were bought with a certain product.

My data going into logstash from a flat file.

 OrderNumber ProductName
    order1   Chicken
    order2   Banana
    order3   Chicken
    order1   Cucumber
    order2   Chicken
    order3   Apples
    order1   Flour
    order2   Rice
    order3   Nuts

As you can see above i have an Product Name of Chicken which occurs in different Order Numbers.

 OrderNumber ProductName
    order1   Chicken
    order3   Chicken
    order2   Chicken

This is what i would like to achieve :

Step 1 : Lookup all order Numbers that contain chicken

 OrderNumber ProductName
    order1   Chicken
    order3   Chicken
    order2   Chicken

Step 2 : if the above orders have chicken in it give me all the other products that was also purchased with it

Result :

     OrderNumber   ProductName
     order1        Cucumber
     order2        Banana
     order3        Apples
     order1        Flour
     order2        Rice
     order3        Nuts

This is what i have tried so far for Step1 :

Query

{
    "query" : {
        "match" : {
        "ProductName" : "Chicken"
}
    }
      }

Result

  "hits" : {
    "total" : 3,
    "max_score" : 11.378191,
    "hits" : [ {
      "_index" : "hello",
      "_type" : "logs",
      "_id" : "AVmxaChupyZuCjD89xPX",
      "_score" : 11.378191,
      "_source" : {
        "message" : "order1\Chicken\r",
        "path" : "C:\\utils\\Elk\\logstash\\bin\\product.log",
        "OrderNumber" : "order1",
        "ProductName" : "Chicken\r"
      }}, {
      "_index" : "hello",
      "_type" : "logs",
      "_id" : "AVmxaChupyZuCjD89xPX",
      "_score" : 11.378191,
      "_source" : {
        "message" : "order3\Chicken\r",
        "path" : "C:\\utils\\Elk\\logstash\\bin\\product.log",
        "OrderNumber" : "order3",
        "ProductName" : "Chicken\r"
      }
   }, {
      "_index" : "hello",
      "_type" : "logs",
      "_id" : "AVmxaChupyZuCjD89xPX",
      "_score" : 11.378191,
      "_source" : {
        "message" : "order2\Chicken\r",
        "path" : "C:\\utils\\Elk\\logstash\\bin\\product.log",
        "OrderNumber" : "order2",
        "ProductName" : "Chicken\r"
      }

I'm very confused as to how to go about completing step 2 as I am very new to Elasticsearch, please help ?

Thanks

解决方案

To search for documents that have order numbers found for Chicken and product names other than Chicken, you can use the following query:

{
  "query" : {
    "and" : [
       {
         "terms" : {
           "OrderNumber" : ["order1", "order2", "order3"]
         }
       },
       {
         "not" : {
           "term" : {
             "ProductName" : "Chicken"
           }
         }
       }
    ]
  }
}
