Amazon web services ElasticSearch嵌套QueryParsingException布尔查询不支持筛选器

我正在使用NEST 2.3.2查询ElasticSearch，需要基于可选布尔值为FollowUpDateTime字段创建一个条件过滤器。如果这个布尔值

                    var containers = new QueryContainer[7];
                    //Size is based on hte number of search parameters.. 
                    var descriptor = new QueryContainerDescriptor<EsNoteModel>();

                    var filters = new QueryContainer[1];
                    var filterdescriptor = new QueryContainerDescriptor<EsNoteModel>();  

       /*...... some code for other parameters here .....*/

        if (hasFollowUpDate.HasValue)
                    {
                        if ((bool) hasFollowUpDate)
                        {
                            //If true shows only with a non-blank follow-up date
                            filters[0] = filterdescriptor.Exists(ff => ff.Field("FollowUpDateTime"));
                        }
                        else
                        {
                            //If false shows only notes with a blank follow-up date
                            filters[0] = filterdescriptor.Missing(ff => ff.Field("FollowUpDateTime"));
                        }
                    }

/*...... CALL to ES below .....*/    

                    var result = ElasticSearchClient.Search<EsNoteModel>(body => body
                        .From(offset - 1)
                        .Size(rows)
                        .Query(q => q
                            .Bool(b => b
                                  .Must(containers)
                                  .Filter(f => f.Bool(t => t.Must(filters)))
                                  )
                                )

                        .Sort(s => s
                            .Field(f => f
                                .Field(p => p.NoteDate)
                                .Order(SortOrder.Descending)))

                        );

• 为true-希望查看日期非空的所有记录
• 是假的-没有日期的记录
• 为空-显示所有记录

以下是我在Nest的资料：

                    var containers = new QueryContainer[7];
                    //Size is based on hte number of search parameters.. 
                    var descriptor = new QueryContainerDescriptor<EsNoteModel>();

                    var filters = new QueryContainer[1];
                    var filterdescriptor = new QueryContainerDescriptor<EsNoteModel>();  

       /*...... some code for other parameters here .....*/

        if (hasFollowUpDate.HasValue)
                    {
                        if ((bool) hasFollowUpDate)
                        {
                            //If true shows only with a non-blank follow-up date
                            filters[0] = filterdescriptor.Exists(ff => ff.Field("FollowUpDateTime"));
                        }
                        else
                        {
                            //If false shows only notes with a blank follow-up date
                            filters[0] = filterdescriptor.Missing(ff => ff.Field("FollowUpDateTime"));
                        }
                    }

/*...... CALL to ES below .....*/    

                    var result = ElasticSearchClient.Search<EsNoteModel>(body => body
                        .From(offset - 1)
                        .Size(rows)
                        .Query(q => q
                            .Bool(b => b
                                  .Must(containers)
                                  .Filter(f => f.Bool(t => t.Must(filters)))
                                  )
                                )

                        .Sort(s => s
                            .Field(f => f
                                .Field(p => p.NoteDate)
                                .Order(SortOrder.Descending)))

                        );

嵌套：QueryParsingException[[customernote]bool查询不支持[filter]]；

您可以使用

QueryContainer

或

FilterContainer

动态执行此操作。下面是我们解决方案中非常类似的一个：

                    var containers = new QueryContainer[7];
                    //Size is based on hte number of search parameters.. 
                    var descriptor = new QueryContainerDescriptor<EsNoteModel>();

                    var filters = new QueryContainer[1];
                    var filterdescriptor = new QueryContainerDescriptor<EsNoteModel>();  

       /*...... some code for other parameters here .....*/

        if (hasFollowUpDate.HasValue)
                    {
                        if ((bool) hasFollowUpDate)
                        {
                            //If true shows only with a non-blank follow-up date
                            filters[0] = filterdescriptor.Exists(ff => ff.Field("FollowUpDateTime"));
                        }
                        else
                        {
                            //If false shows only notes with a blank follow-up date
                            filters[0] = filterdescriptor.Missing(ff => ff.Field("FollowUpDateTime"));
                        }
                    }

/*...... CALL to ES below .....*/    

                    var result = ElasticSearchClient.Search<EsNoteModel>(body => body
                        .From(offset - 1)
                        .Size(rows)
                        .Query(q => q
                            .Bool(b => b
                                  .Must(containers)
                                  .Filter(f => f.Bool(t => t.Must(filters)))
                                  )
                                )

                        .Sort(s => s
                            .Field(f => f
                                .Field(p => p.NoteDate)
                                .Order(SortOrder.Descending)))

                        );

var query = new List<QueryContainer>
{
    Query<AlertForReporting>.Range(r => r.OnField(f => f.AlertDate)
                                          .Greater(start.ToEPCISFormat())
                                          .Lower(end.ToEPCISFormat())
        )
};


var result = ElasticClient.Search<AlertForReporting>(s =>
                        s.Size(0)
                            .Query(q =>
                                q.Bool(b =>
                                        b.Must(query.ToArray())
                                    )
                            ));

var query=新列表
{
Query.Range（r=>r.OnField（f=>f.AlertDate）
.greer（start.ToEPCISFormat（））
.Lower（end.ToEPCISFormat（））
)
};
var result=ElasticClient.Search（s=>
s、 大小（0）
.Query（q=>
q、 布尔（b=>
b、 必须（query.ToArray（））
)
));

显然，我们在.NET 4.0项目中有以下参考

                    var containers = new QueryContainer[7];
                    //Size is based on hte number of search parameters..

                    var filterdescriptor = new QueryContainerDescriptor<EsNoteModel>();  

       /*...... some code for other parameters here .....*/

        if (hasFollowUpDate.HasValue)
                    {
                        if ((bool) hasFollowUpDate)
                        {
                            //If true shows only with a non-blank follow-up date
                            filters[0] = filterdescriptor.Exists(ff => ff.Field("FollowUpDateTime"));
                        }
                        else
                        {
                            //If false shows only notes with a blank follow-up date
                            filters[0] = filterdescriptor.Missing(ff => ff.Field("FollowUpDateTime"));
