如何按类型过滤建议查询

Question

假设我已经映射了多个类型，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 here 关于 Context Suggester 的内容。这也有效，但现在我找不到这两种类型，因为我必须设置上下文。将上下文留空 returns 没有结果。如何快刀斩乱麻？是否有与使用 Context Suggester 不同的方法？

这是我为 Company 映射的（稍微缩短了一点）：

 "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"
                ]
             }
          }
       }
    }
 }

Answer 1

能够通过 context suggester 实现。我将上下文中的 path 设置为 _type。

示例：

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) 示例文档

  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：输入公司

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：输入公司和客户

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