c# - 在 Elasticsearch 中将英语分析器添加到类型

Question

我想将English分析器添加到我的ElasticSearch分析器中的类型。
就像是:

    [ElasticsearchType(Name = "blogpost", IdProperty = "Id")]
public class BlogPost
{
    [String]
    public Guid Id { get; set; }

    [String]
    public string Title { get; set; }

    [String(Analyzer = LanguageAnalyzers.English, TermVector = TermVectorOption.WithOffsets)]
    public string Body { get; set; }
}

我正在使用C#NEST 2.x API
这里的错误部分是:我编写的“LanguageAnalyzers.English”。

关于如何正确纠正的任何建议？

Answer 1

可以用 "english" analyzer引用英语分析器

[ElasticsearchType(Name = "blogpost", IdProperty = "Id")]
public class BlogPost
{
    [String]
    public Guid Id { get; set; }

    [String]
    public string Title { get; set; }

    [String(Analyzer = "english", TermVector = TermVectorOption.WithOffsets)]
    public string Body { get; set; }
}

client.CreateIndex("blogposts", c => c
    .Mappings(m => m
        .Map<BlogPost>(mm => mm
            .AutoMap()
        )
    )
);

产量

{
  "mappings": {
    "blogpost": {
      "properties": {
        "id": {
          "type": "string"
        },
        "title": {
          "type": "string"
        },
        "body": {
          "type": "string",
          "term_vector": "with_offsets",
          "analyzer": "english"
        }
      }
    }
  }
}
