C# 弹性搜索嵌套客户端未应用boost

我正在调查一个搜索结果与预期不符的bug，并发现这是因为没有应用boost

查询是使用NEST（6.6.0）生成的，使用以下代码：

queryContainer = new MultiMatchQuery
{
    Fuzziness = Fuzziness.Auto,
    Query = querystring,
    Type = TextQueryType.BestFields,
    Fields = Infer.Fields<RecipeSearchModel>(
        f1 => Infer.Field<RecipeSearchModel>(f => f.Title, 5),
        f2 => f2.Description,
        f3 => Infer.Field<RecipeSearchModel>(f => f.Ingredients, 3),
        f4 => f4.Method,
        f5 => Infer.Field<RecipeSearchModel>(f => f.Image.Alt, 4))
};

这似乎是正确的，我可以从中看出，为什么这不起作用？

确实看起来boost在某个地方被忽略了，这是github问题的链接。 现在，您可以尝试另一种语法：

queryContainer = new MultiMatchQuery
{
    Fuzziness = Fuzziness.Auto,
    Query = "query",
    Type = TextQueryType.BestFields,
    Fields = Infer.Fields<RecipeSearchModel>()
        .And(Infer.Field<RecipeSearchModel>(f => f.Title, 5))
        .And<RecipeSearchModel>(f => f.Description)
        .And(Infer.Field<RecipeSearchModel>(f => f.Ingredients, 3))
        .And<RecipeSearchModel>(f => f.Method)
        .And(Infer.Field<RecipeSearchModel>(f => f.Image.Alt, 4))
};

使用NEST 6.6.0进行测试

希望能有所帮助。

非常感谢。你有关于github问题的链接吗？当然，给我5分钟的时间来完成它啊，对不起。只是注意到你几分钟前才回答！

queryContainer = new MultiMatchQuery
{
    Fuzziness = Fuzziness.Auto,
    Query = "query",
    Type = TextQueryType.BestFields,
    Fields = Infer.Fields<RecipeSearchModel>()
        .And(Infer.Field<RecipeSearchModel>(f => f.Title, 5))
        .And<RecipeSearchModel>(f => f.Description)
        .And(Infer.Field<RecipeSearchModel>(f => f.Ingredients, 3))
        .And<RecipeSearchModel>(f => f.Method)
        .And(Infer.Field<RecipeSearchModel>(f => f.Image.Alt, 4))
};

{
  "query": {
    "multi_match": {
      "fields": [
        "title^5",
        "description",
        "ingredients^3",
        "method",
        "image.alt^4"
      ],
      "fuzziness": "AUTO",
      "query": "query",
      "type": "best_fields"
    }
  }
}
