Question

我是NEST ElasticSearch的新手，并且有一个Class命名文档，如下所示

[ElasticType(Name = "EnterpriseSearch.Document")]
public class Document
{

    public Document()
    {
    }

    [ElasticProperty(Type = FieldType.Integer, Index = FieldIndexOption.NotAnalyzed)]
    public int DocumentId { get; set; }

    [ElasticProperty(Type = FieldType.String, Index = FieldIndexOption.NotAnalyzed)]
    public string Source { get; set; }

    [ElasticProperty(Type = FieldType.String, Index = FieldIndexOption.NotAnalyzed)]
    public string Name { get; set; }

    [ElasticProperty(Type = FieldType.String, Index = FieldIndexOption.Analyzed, IndexAnalyzer = "snowballstopAnalyzers", TermVector = TermVectorOption.WithPositionsOffsets)]
    public string Documents { get; set; }
}

我正在创建索引并尝试使用下面的代码映射它。

public void CreateDocumentIndex(string indexName = null)
{
    if (!this.client.IndexExists(indexName).Exists)
    {
        IndexSettings settings = GetIndexSettings();

        this.client.CreateIndex(indexName, c => c
            .InitializeUsing(settings)
            .AddMapping<Document>
            (m => m.Properties(ps => ps.String(a => a.Name(o => o.Documents)))));

        this.client.Map<Document>(p => p.MapFromAttributes());
    }
}

基本上我想将IndexAnalyzer应用于类Document中的Documents属性。但它没有用。在调试时，我注意到如果我使用下面的代码检查属性，则Mappings计数为零

var r = this.client.GetIndexSettings(i => i.Index(indexName));

任何帮助？

检查索引的映射，如下所示：

http://10.0.0.11:9200/{index_name}/{mappingType}/_mapping?pretty

大多数情况下，映射被分析器的错误实现“杀死”。如果你能够提供你所拥有的完整示例，那将更容易为你提供帮助。

NEST ELASTICSEARCH映射不起作用
