Elasticsearch 2.3 - Nest - 使用语音分析器

Question

我正在使用 Elasticsearch 2.3 - Nest API 来搜索数据。我正在为文档使用属性映射。我想知道如何通过属性映射来使用语音分析器。

文档类：

[ElasticsearchType(Name = "contact", IdProperty = nameof(EntityId))]
public class ESContactSearchDocument
{
    [String(Name = "entityid")]
    public string EntityId { get; set; }

    [String(Name = "id")]
    public string Id { get; set; }

    [String(Name = "name")]
    public string Name { get; set; }

    [String(Name = "domain")]
    public string Domain { get; set; }

    [String(Name = "description")]
    public string Description { get; set; }

    [String(Name = "email")]
    public string Email { get; set; }

    [String(Name = "firstname", Analyzer = "phonetic")]
    public string FirstName { get; set; }

    [String(Name = "lastname", Analyzer = "phonetic")]
    public string LastName { get; set; }
}

索引创建和插入：

var createIndexResponse = serviceClient.CreateIndex(indexName, c => c.Mappings(m => m.Map<ESContactSearchDocument>(d => d.AutoMap())));

var indexManyResponse = await serviceClient.IndexManyAsync(ESMapper.Map<TDocument, ESContactSearchDocument>(documentsBatch), indexName, typeName);

ESMapper 仅用于从一种类型转换为另一种类型。

结果映射：

{
  "contact-uklwcl072": {
    "mappings": {
      "contact": {
        "properties": {
          "description": {
            "type": "string"
          },
          "domain": {
            "type": "string"
          },
          "email": {
            "type": "string"
          },
          "entityid": {
            "type": "string"
          },
          "firstname": {
            "type": "string"
          },
          "id": {
            "type": "string"
          },
          "lastname": {
            "type": "string"
          },
          "name": {
            "type": "string"
          }
        }
      }
    }
  }
}

我也安装了Phonetic Analysis Plugin

Take a look at the automapping documentation;您需要将分析器的名称分配给属性上的Analyzer 属性

public class Document
{
    [String(Analyzer="phonetic")]
    public string Name {get; set;}
}

然后在映射您的文档类型时调用AutoMap()，例如创建索引时

client.CreateIndex("index-name", c => c
    .Mappings(m => m
        .Map<Document>(d => d
            .AutoMap()
        )
    )
);

产量

{
  "mappings": {
    "document": {
      "properties": {
        "name": {
          "type": "string",
          "analyzer": "phonetic"
        }
      }
    }
  }
}
