使用 Object Initializer 语法创建 MultiMatchQuery 时出错

Question

我正在使用 Nest 2.2.0 并尝试构建一个多匹配查询，如下所示：

var searchQuery = new MultiMatchQuery() 
{
    Fields = Field<Product>(p=>p.SKUName, 2),
    Query = "hello world"
};

当我运行它然而，它returns：

The non-generic type 'Nest.Field' cannot be used with type arguments.

我不明白为什么会收到错误消息，因为我或多或少是直接从 https://www.elastic.co/guide/en/elasticsearch/client/net-api/2.x/multi-match-usage.html#_object_initializer_syntax_example_35 上的文档中获取此查询的。

以防万一，我将产品定义如下：

[ElasticsearchType(Name="product", IdProperty="Id")]
public class Product
{
    [Nest.Number(Store = true)]
    public int Id {get;set;}

    [String(Name="name", Store = true, Index=FieldIndexOption.Analyzed)]
    public string SKUName { get; set; }
}

有人能帮忙吗？

Answer 1

您要查找的 Field 类型是 Nest.Infer.Field

var searchQuery = new MultiMatchQuery()
{
    Fields = Nest.Infer.Field<Product>(p => p.SKUName, 2),
    Query = "hello world"
};

client.Search<Product>(new SearchRequest { Query = searchQuery });
