同义词分析器不工作

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": {}
}
}

My synonym.txt文件位于configmain 里面的文件夹elasticsearch folder.

这是我的查询：

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

中的话synonym.txt are: 我们，美国，美国.

所以这是行不通的。有趣的是搜索正常进行，except因为当我输入其中的任何单词时synonym.txt文件。例如，当我通常输入us进入搜索，我会得到结果。有了这个分析仪，us没有给我任何东西。

我已经搞定了close and open到我的ES服务器，仍然不起作用。

EDIT

一个例子document:

{
    "_index": "countries",
    "_type": "country",
    "_id": "57aabeb80057405968de152b",
    "_score": 1,
    "_source": {
      "countryName": "United States"
    }

的例子searchInput（这是来自前端的）：

united states

EDIT #2:

这是我更新的索引配置文件：

{
"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所述文档进行搜索时，synonym分析仪对我不起作用。

EDIT #3

以下是索引中的 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"
        }
    }]
}
}

你很接近，但我建议仔细阅读文档中的这一部分 https://www.elastic.co/guide/en/elasticsearch/guide/current/synonyms.html更好地了解此功能。

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"
        }
      }
    }
  }
}

您需要删除索引并使用上面的映射重新创建它。 然后使用这个查询：

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