Question

我将以下属性应用于我的linq to sql类：

[Document(MetadataType = typeof(SomeObjectMetadata))]
public partial class SomeObject
{
}

这是元数据代码：

public class SomeObjectMetadata
{

    [Field(FieldIndex.Tokenized, FieldStore.Yes, IsKey = true)]  
    private object ProductId { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes, IsDefault = true)]  
    private object Name { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)]  
    private object Description { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)] 
    private object Breadcrumb { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)] 
    private object Tab1Content { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)] 
    private object Tab2Content { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)] 
    private object Tab3Content { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)] 
    private object Tab4Content { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)] 
    private object Tab5Content { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)] 
    private object Manufacturer { get; set; }

}

索引存储写得很好，但是当我尝试搜索它时，我得到了标题中显示的错误。以下是搜索示例：

        var qry = from r in _dbi.Get<SomeObject>()
                  where r.Description.Like(search)
                  select r;

在枚举“qry”时，会抛出异常“类必须至少将一个字段定义为默认搜索字段”。

哇，我是个白痴。元数据字段是私有的。这当然解决了这个问题：

public class Catalog_ProductMetadata
{

    [Field(FieldIndex.Tokenized, FieldStore.Yes, IsKey = true)]
    public object ProductId { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes, IsDefault = true)]
    public object Name { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)]
    public object Description { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)]
    public object Breadcrumb { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)]
    public object Tab1Content { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)]
    public object Tab2Content { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)]
    public object Tab3Content { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)]
    public object Tab4Content { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)]
    public object Tab5Content { get; set; }

    [Field(FieldIndex.Tokenized, FieldStore.Yes)]
    public object Manufacturer { get; set; }

}

Linq to Lucene错误：“类必须至少将一个字段定义为默认搜索字段”
