嵌套弹性搜索按枚举值排序特定顺序

Question

elasticSearch中的产品模型是这样的：

public class Product
{
    public int ProductId { get; set; }

    public string BrandName { get; set; }

    public string Name { get; set; }

    public ProductStatus ProductStatus { get; set; }
}

和ProductStatus枚举指定产品状态

public enum ProductStatus
{
    Available = 1,
    UnAvailable = 2,
    CommingSoon = 3,
    OutOfOrder = 4
}

我希望根据此订单对产品搜索结果进行排序：可用，CommingSoon，UnAvailable和OutOfOrder，此订单可能会稍后更改， 如何在elasticSearch和NEST中实现这种可能性

我认为您可以对每个变量进行功能评分，然后对功能评分求和

function_score": {
    "query": {},
    "boost": "boost for the whole query",
    "functions": [
        {
            "filter": {},
            "FUNCTION": {}, 
            "weight": number
        },
        {
            "FUNCTION": {} 
        },
        {
            "filter": {},
            "weight": number
        }
    ],
    "max_boost": number,
    "score_mode": "(multiply|max|...)",
    "boost_mode": "(multiply|replace|...)",
    "min_score" : number
}
