elasticsearch - 如何按类型过滤建议查询

Question

假设我已经映射了多种类型，例如Company和Customer。这些类型与建议字段映射。当我对这两种类型执行suggest查询时，一切正常。现在，我想限制查询以查找一种类型的结果。我阅读了有关上下文建议程序的here。这也可以，但是现在我找不到这两种类型，因为我必须设置上下文。将上下文保留为空不会返回任何结果。如何削减高迪氏结？除了使用Context Suggester之外，还有其他方法吗？

这是我对Company的映射(略有缩短):

 "company": {
    "dynamic": "false",
    "_id": {
       "path": "Id"
    },
    "properties": {
       "name": {
          "type": "string"
       },
       "suggest": {
          "type": "completion",
          "analyzer": "simple",
          "payloads": true,
          "preserve_separators": true,
          "preserve_position_increments": true,
          "max_input_length": 50,
          "context": {
             "type": {
                "type": "category",
                "path": "type",
                "default": [
                   "company"
                ]
             }
          }
       }
    }
 }

能够通过上下文提示器实现它。我将上下文中的path设置为_type。

例:

1)映射

put test/company/_mapping
{
 "company": {

    "properties": {
       "name": {
          "type": "string"
       },
       "suggest": {
          "type": "completion",
          "analyzer": "simple",
          "payloads": true,
          "preserve_separators": true,
          "preserve_position_increments": true,
          "max_input_length": 50,
          "context": {
             "type": {
                "type": "category",
                "path": "_type"
             }
          }
       }
    }
 }
}

put test/customer/_mapping
{
 "customer": {

    "properties": {
       "name": {
          "type": "string"
       },
       "suggest": {
          "type": "completion",
          "analyzer": "simple",
          "payloads": true,
          "preserve_separators": true,
          "preserve_position_increments": true,
          "max_input_length": 50,
          "context": {
             "type": {
                "type": "category",
                "path": "_type"
             }
          }
       }
    }
 }
}

2)范例文件

  PUT test/company/1
    {
        "name": "hello company",
        "suggest": {
            "input": ["hello", "hello company"]
        }
    }

    PUT test/customer/1
    {
        "name": "hello customer",
        "suggest": {
            "input": ["hello again", "hello customer"]
        }
    }

3)建议:类型公司

POST test/_suggest
{
        "suggest" : {
            "text" : "hel",
            "completion" : {
            "field" : "suggest",
            "size": 10,
            "context": {
                "type": ["customer"]
            }
        }
    }
}

4)建议:键入客户

post test/_suggest
{
        "suggest" : {
            "text" : "hel",
            "completion" : {
            "field" : "suggest",
            "size": 10,
            "context": {
                "type": ["company"]
            }
        }
    }
}

5)建议:键入公司和客户

post test/_suggest
{
        "suggest" : {
            "text" : "hel",
            "completion" : {
            "field" : "suggest",
            "size": 10,
            "context": {
                "type": ["company","customer"]
            }
        }
    }
}
