使用NEST 7的功能分数查询中的弹性搜索过滤器

问题描述

在我的情况下，我必须先显示库存商品，然后鼓励某些品牌，也鼓励某些品牌。

我正在尝试使用功能得分查询https://www.elastic.co/guide/en/elasticsearch/client/net-api/5.x/function-score-query-usage.html

来实现它

我尝试了文档代码，它返回有效结果。库存物品排在第一位，阻止品牌进入预期的最后一页。 但是我的问题是鼓励品牌不要排在第一位。

这是我的代码，其中包含一些示例品牌，例如，以库存商品为第一，而Orange品牌为第一。

var query = new FunctionscoreQuery()
            {
                Name = "product_query",Boost = 5,Query = new MatchAllQuery { },Functions = new List<IscoreFunction>
                            {
                                //new RandomscoreFunction
                                //{
                                //    Filter = new MatchQuery { Field = "ManufacturerName",Query = "Apple" },//    Weight = 35
                                //},//new RandomscoreFunction
                                //{
                                //    Filter = new MatchQuery { Field = "ManufacturerName",Query = "Orange" },//    Weight = 52
                                //},new WeightFunction
                                {
                                    Filter = new MatchQuery { Field = "ManufacturerName",Weight = 25
                                },Weight = 42
                                },new WeightFunction 
                                {
                                    Filter = new MatchQuery{ Field = "StockAvailability",Query = "true"},Weight = 42
                                }
                           },MaxBoost = 42,scoreMode = FunctionscoreMode.Max,BoostMode = FunctionBoostMode.Multiply,Minscore = 42
            };

这是我的查询
