Nest QueryContainer 用法

Question

您好，我可以使用 DateRangeQuery 数组填充 QueryContainer，如下所示 QueryContainer marriageDateQuerys = null;

        if (!string.IsNullOrEmpty((item.marriage_date)))
            {
                DateRangeQuery query = new DateRangeQuery();
                query.Field = "marriages.marriage_date";
                query.Name = item.marriage_date;
                query.GreaterThanOrEqualTo = item.marriage_date;
                query.LessThanOrEqualTo = item.marriage_date;

                marriageDateQuerys &= query;
            }

但是当我使用 QueryContainer 来使用 MatchQuery/TermQuery 填充数据时，它并没有发生。

           QueryContainer marriageSpouseFirstNameQuerys = null;  


            if (!string.IsNullOrEmpty((item.spouse_first_name)))
            {
                MatchQuery query = new MatchQuery();
                query.Field = "marriages.spouse_first_name";
                query.Name = item.spouse_first_name;
                marriageSpouseFirstNameQuerys &= query;
            }

查询对象是在最后一个 if 条件中创建的，但 marriageSpouseFirstNameQuerys 没有填充相同的内容。我什至试过 marriageSpouseFirstNameQuerys += query;但没有任何成功

没试过，但你可以试试这样的

              Query = new QueryContainer(new BoolQuery
                    {
                        Must = new List<QueryContainer>
                        {
                            new MatchQuery
                            {
                                //props
                            },
                            new TermQuery
                            {
                                Field = field
                                Value = value
                            },
                        }
                    })

在使用 eyildiz answer 进行更改后，以下代码对我有用

       if (!string.IsNullOrEmpty((item.spouse_last_name)))
                {
                    marriageSpouseLastNameQuery = new QueryContainer(
                        new MatchQuery
                        {
                            Field = "marriages.spouse_last_name",
                            Query = item.spouse_last_name
                        });
                    lstmarriageSpouseLastNameQuerys.Add(marriageSpouseLastNameQuery);
                }
