c# - Linq to Lucene 错误 : "Classes must define at least one field as a default search field"

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，出现标题中显示的错误。这是一个示例搜索:

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

枚举“qry”时，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(private)的。当然，这可以解决问题:

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; }

}
