ElasticSearch:设置搜索分析器时必须设置Analyzer on字段

elasticsearch

Nate Uni · 技术社区 · 6 年前

我已经阅读了es(<2)的早期版本,其中需要将“token_analyzer”密钥更改为“analyzer”。但不管我做什么我还是会犯这个错误:

"type": "mapper_parsing_exception",
"reason": "analyzer on field [email] must be set when search_analyzer is set"

当我得到错误时,通过put函数传递给es的是:

{ 
    "settings": {
      "analysis": {
        "analyzer": {
          "my_email_analyzer": {
            "type": "custom",
            "tokenizer": "uax_url_email",
            "filter": ["lowercase", "stop"]
          }
        }
      }
    },
    "mappings" : {
        "uuser": {
            "properties": {
                "email": {
                  "type": "text",
                  "search_analyzer": "my_email_analyzer",
                  "fields": {
                    "email": { 
                      "type":  "text",
                      "analyzer": "my_email_analyzer"
                    }
                  }
                },
                "facebookId": {
                    "type": "text"
                },
                "name": {
                    "type": "text"
                },
                "profileImageUrl": {
                    "type": "text"
                },
                "signupDate": {
                    "type": "date"
                },
                "username": {
                    "type": "text"
                }
                ,
                "phoneNumber": {
                    "type": "text"
                }
            }

        }
    }
}

有什么问题吗?

因为你指定了 搜索分析器 对于字段,还必须指定 分析仪 在索引时使用。例如,在指定搜索分析器的位置下添加此行:

"analyzer": "standard",

给你这个:

{ 
    "settings": {
      "analysis": {
        "analyzer": {
          "my_email_analyzer": {
            "type": "custom",
            "tokenizer": "uax_url_email",
            "filter": ["lowercase", "stop"]
          }
        }
      }
    },
    "mappings" : {
        "uuser": {
            "properties": {
                "email": {
                  "type": "text",
                  "search_analyzer": "my_email_analyzer",
                  "analyzer": "standard",
                  "fields": {
                    "email": { 
                      "type":  "text",
                      "analyzer": "my_email_analyzer"
                    }
                  }
                },
                "facebookId": {
                    "type": "text"
                },
                "name": {
                    "type": "text"
                },
                "profileImageUrl": {
                    "type": "text"
                },
                "signupDate": {
                    "type": "date"
                },
                "username": {
                    "type": "text"
                }
                ,
                "phoneNumber": {
                    "type": "text"
                }
            }

        }
    }
}
