elasticsearch - 自定义分析器不工作 Elasticsearch

Question

{
  "_source": {
    "enabled": false
  },
  "analysis": {
    "analyzer": {
      "default": {
        "type": "custom",
        "tokenizer": "uax_url_email",
        "filter": "lowercase,standard,stop"
      }
    }
  },
  "mappings": {
    "table": {
      "properties": {
        "field1": {
          "type": "string",
          "include_in_all": false,
          "index": "no"
        },
        "field2": {
          "type": "long",
          "include_in_all": false,
          "index": "no"
        },
        "field3": {
              "type": "string",
              "index": "analyzed"
            }
      }
    }
  }
}

分析仪在测试时似乎不起作用。分析器不应该索引停用词，它还应该索引整个电子邮件地址。当我“测试分析​​器”并输入“ jack 很好”时，所有三个单词的索引都会发生。我不希望它索引英语中的停用词，例如“and”、“is”等。

您将字段设置为 "index": "no"并禁用 include_in_all .您如何期望将某些内容放入索引中？引自 documentation :

no means that it won’t be searchable at all (as an individual field; it may still be included in _all). Setting to no disables include_in_all.

而实际的 settings应该是这样的(您的索引定义中缺少 "settings"):

{
  "_source": {
    "enabled": false
  },
  "settings": {
    "analysis": {
      "analyzer": {
        "default": {
          "type": "custom",
          "tokenizer": "uax_url_email",
          "filter": "lowercase,standard,stop"
        }
      }
    }
  },
  "mappings": {
    "table": {
      "properties": {
        "field1": {
          "type": "string",
          "include_in_all": false,
          "index": "no"
        },
        "field2": {
          "type": "long",
          "include_in_all": false,
          "index": "no"
        },
        "field3": {
          "type": "string",
          "index": "analyzed"
        }
      }
    }
  }
}
