自定义分析器不工作 Elasticsearch

{

        "type": "custom",

        "filter": "lowercase,standard,stop"
      }

  "mappings": {

        "field1": {
          "type": "string",
          "include_in_all": false,
          "index": "no"
        },
        "field2": {
          "type": "long",
          "include_in_all": false,
          "index": "no"
        },
        "field3": {
              "type": "string",
              "index": "analyzed"
            }

    }
  }
}

测试时分析仪似乎不工作。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 "TEST ANALYZER" 并键入 "Jack is fine" 时，将对所有三个词进行索引。我不希望它索引英语中的停用词，例如 "and"、"is" 等

Answer 1

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"
        }
      }
    }
  }
}
