同义词分析器不起作用 [英] Synonym analyzer not working

问题描述

这是我的设置:

{
"countries": {
"aliases": {},
"mappings": {
  "country": {
    "properties": {
      "countryName": {
        "type": "string"
      }
    }
  }
},
"settings": {
  "index": {
    "creation_date": "1472140045116",
    "analysis": {
      "filter": {
        "synonym": {
          "ignore_case": "true",
          "type": "synonym",
          "synonyms_path": "synonym.txt"
        }
      },
      "analyzer": {
        "synonym": {
          "filter": [
            "synonym"
          ],
          "tokenizer": "whitespace"
        }
      }
    },
    "number_of_shards": "5",
    "number_of_replicas": "1",
    "uuid": "7-fKyD9aR2eG3BwUNdadXA",
    "version": {
      "created": "2030599"
    }
  }
},
"warmers": {}
}
}

我的 synonym.txt 文件位于主 elasticsearch 文件夹内的 config 文件夹中.

My synonym.txt file is in the config folder inside the main elasticsearch folder.

这是我的查询:

query: {
    query_string: {
        fields: ["countryName"],
        default_operator: "AND",
        query: searchInput,
        analyzer: "synonym"
        }
     }

synonym.txt 中的单词是:美国，美国.

The words in synonym.txt are: us, u.s., united states.

所以这不起作用.有趣的是，当我在 synonym.txt 文件中输入任何单词时，搜索工作正常， 除外.因此，例如，当我通常在搜索中键入我们时，我会得到结果.使用此分析仪，我们不会给我任何东西.

So this doesn't work. What's interesting is that search works as normal, except for when I enter any of the words in the synonym.txt file. So for example, when I usually type in us into the search, I would get results. With this analyzer, us doesn't give me anything.

我已经对我的ES服务器进行了 close 和 open ，但仍然无法正常工作.

I've done close and open to my ES server, and still it doesn't work.

    "_score": 1,

      "countryName": "United States"
    }

searchInput 的示例(来自前端):

Example of searchInput (this is coming from the front-end):

美国

编辑#2 :

这是我更新的索引配置文件:

Here is my updated index config file:

{
"countries": {
    "aliases": {},
    "mappings": {},
    "settings": {
        "index": {
            "number_of_shards": "5",
            "creation_date": "1472219634083",
            "analysis": {
                "filter": {
                    "synonym": {
                        "ignore_case": "true",
                        "type": "synonym",
                        "synonyms_path": "synonym.txt"
                    }
                },
                "analyzer": {
                    "synonym": {
                        "filter": [
                            "synonym"
                        ],
                        "tokenizer": "whitespace"
                    }
                }
            },
            "country": {
                "properties": {
                    "countryName": {
                        "type": "string",
                        "analyzer": "synonym"
                    },
                    "number_of_replicas": "1",
                    "uuid": "50ZwpIVFTqeD_rJxlmd59Q",
                    "version": {
                        "created": "2030599"
                    }
                }
            },
            "warmers": {}
        }
    }
}
}

当我尝试添加文档并对这些文档进行搜索时，同义词分析器对我不起作用.

When I try adding documents, and doing a search on said documents, the synonym analyzer does not work for me.

编辑#3

索引中有2个文档:

{
"took": 3,
"timed_out": false,
"_shards": {
    "total": 5,
    "successful": 5,
    "failed": 0
},
"hits": {
    "total": 2,
    "max_score": 1,
    "hits": [{
        "_index": "stocks",
        "_type": "stock",
        "_id": "2",
        "_score": 1,
        "_source": {
            "countryName": "United States"
        }
    }, {
        "_index": "stocks",
        "_type": "stock",
        "_id": "1",
        "_score": 1,
        "_source": {
            "countryName": "Canada"
        }
    }]
}
}

推荐答案

您很亲密，但我建议您仔细阅读

You are close, but I suggest reading thoroughly this section from the documentation to understand better this functionality.

作为解决方案:

PUT /countries
{
  "mappings": {
    "country": {
      "properties": {
        "countryName": {
          "type": "string",
          "analyzer": "synonym"
        }
      }
    }
  },
  "settings": {
    "analysis": {
      "filter": {
        "synonym": {
          "ignore_case": "true",
          "type": "synonym",
          "synonyms_path": "synonym.txt"
        }
      },
      "analyzer": {
        "synonym": {
          "filter": [
            "lowercase",
            "synonym"
          ],
          "tokenizer": "whitespace"
        }
      }
    }
  }
}

您需要删除索引，然后使用上面的映射重新创建索引.然后使用以下查询:

You need to delete the index and create it again with the mapping above. Then use this query:

  "query": {
    "query_string": {
      "fields": [
        "countryName"
      ],
      "default_operator": "AND",
      "query": "united states"
    }
  }
