NEST ELASTICSEARCH Mappings 不起作用

Question

我是 NEST ElasticSearch 的新手，并且有一个名为文档的类，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以下代码对其进行映射。

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，我想应用索引分析器来属性类文档中的文档。但它不起作用。调试时，我注意到如果我使用以下代码检查属性，映射计数为零

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

有什么帮助吗？

像这样检查索引的映射：

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"。如果你能把你拥有的完整例子，它会更容易帮助你。
