我正在使用NEST 2.3.2来查询ElasticSearch，需要根据可选的布尔值为FollowUpDateTime字段创建条件过滤器。如果那个布尔
这是我在Nest中所拥有的：
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)))
);
问题是上面的查询生成了错误。请参阅以下内容：

如您所见，错误报告“嵌套：QueryParsingException [[customernote] bool查询不支持[filter]];”我在这个例子中做错了什么想法？这是否正确使用了filter子句？

答案 0 :(得分：1)
显然我们在.NET 4.0项目中有以下对
的引用您正在使用的客户端，但服务器是1.5.2（因为那是 只有aws elasticsearch服务提供的版本，你 似乎正在使用）
见下文 - 它有效：
var query = new QueryContainer[8];//Size is based on hte number of search parameters
var descriptor = new QueryContainerDescriptor<EsNoteModel>();
/*........... skipping here some code for other parameters ..........*/
if (hasFollowUpDate.HasValue)
{
if ((bool) hasFollowUpDate)
{
//If true shows only with a non-blank follow-up date
query[7] = descriptor.Filtered(p => p.Filter(f => f.Exists(r => r.Field(u => u.FollowUpDateTime))));
}
else
{
////If false shows only notes with a blank follow-up date
query[7] = descriptor.Filtered(p => p.Filter(f => f.Missing(r => r.Field(u => u.FollowUpDateTime))));
}
}
var result = ElasticSearchClient.Search<EsNoteModel>(body => body
.From(offset - 1)
.Size(rows)
.Query(q => q
.Bool(b => b
.Must(query)
)
)
.Sort(s => s
.Field(f => f
.Field(p => p.NoteDate)
.Order(SortOrder.Descending)))
);
所以简单地将单词BOOL替换为Filtered - 就可以了解

您可以使用 public char [] HEB(string N)
{
或foreach(char c in HEB("אבג"))
{
line += c.ToString();
}
动态执行此操作。这是我们解决方案中非常类似的一个：
QueryContainer
