使用 NEST 排序时出错（未知字段 ignore_unmapped）
Error while sorting with NEST (unknown field ignore_unmapped)
我在使用 NEST 排序时遇到此错误（[field_sort] 未知字段 [ignore_unmapped]）。原因就在这个地方，评论了就万事大吉了。
请帮助我理解这个问题。
internal static void SortBy(string sortColumn, string sortType, SearchDescriptor<BaseIndexerObject> searchDescriptor)
{
Action<string, string, SearchDescriptor<BaseIndexerObject>> algorithm;
bool algorithmExists = sortAlgorithms.TryGetValue(sortColumn, out algorithm);
if (algorithmExists)
{
algorithm(sortColumn, sortType, searchDescriptor);
return;
}
searchDescriptor.Sort(sortFieldDescriptor =>
{
if (sortType == "asc")
{
sortFieldDescriptor.Ascending(asc => sortColumn);
}
else
{
sortFieldDescriptor.Descending(desc => sortColumn);
}
ParameterExpression param = Expression.Parameter(typeof(BaseIndexerObject), "x");
Expression<Func<BaseIndexerObject, object>> lambda =
Expression.Lambda<Func<BaseIndexerObject, object>>(
Expression.Convert(Expression.PropertyOrField(param, sortColumn), typeof(object)), param);
sortFieldDescriptor.Field(f => f.Field(lambda).IgnoreUnmappedFields());
return sortFieldDescriptor;
});
}

根据 RFC2616，HTTP/400 响应将不会被缓存，无论存在什么缓存 headers。
此响应未指定明确的 HTTP 缓存生命周期信息，也未指定 Last-Modified 日期。启发式到期通常基于 Last-Modified 日期。缺少 Last-Modified，此响应可能会在每次使用或每次浏览时重新验证 session，具体取决于浏览器配置。
此响应既不包含 ETAG 也不包含 Last-Modified 时间。这将阻止此响应的有条件重新验证。
我不太清楚查询的意图是什么，但是 ignore_unmapped 看起来只有 geo distance sorting 支持。
与其他字段排序，unmapped_type property can be used。我认为您正在寻找类似以下的内容
private static void Main()
{
var pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));
var defaultIndex = "posts";
var settings = new ConnectionSettings(pool)
.DefaultIndex(defaultIndex);
var client = new ElasticClient(settings);
var sortType = "asc";
var sortColumn = "TimeReal";
var response = client.Search<Post>(s => s
.Sort(sortFieldDescriptor =>
{
// TODO: probably cache/source generate the mapping of PropertyInfo -> FieldType
var property = typeof(BaseIndexerObject).GetProperty(sortColumn);
FieldType? unmappedType = null;
switch (property.PropertyType.FullName)
{
case "System.Int32":
unmappedType = FieldType.Integer;
break;
// TODO: fill in other relevant Type -> FieldType mappings
}
sortFieldDescriptor.Field(f => f
.Field(sortColumn)
.UnmappedType(unmappedType)
.Order(sortType == "asc" ? SortOrder.Ascending : SortOrder.Descending)
);
return sortFieldDescriptor;
})
);
}
public class BaseIndexerObject
{
public int TimeReal { get; set; }
}
生成查询
POST http://localhost:9200/posts/_search?pretty=true&typed_keys=true
{
"sort": [
{
"TimeReal": {
"unmapped_type": "integer",
"order": "asc"
}
}
]
}
(顺便说一句，我会看一下用于生成查询的代码。生成的内容中有很多多余的 match_all 查询，这会使查询解析不必要地复杂化服务器).

根据 RFC2616，HTTP/400 响应将不会被缓存，无论存在什么缓存 headers。 此响应未指定明确的 HTTP 缓存生命周期信息，也未指定 Last-Modified 日期。启发式到期通常基于 Last-Modified 日期。缺少 Last-Modified，此响应可能会在每次使用或每次浏览时重新验证 session，具体取决于浏览器配置。
此响应既不包含 ETAG 也不包含 Last-Modified 时间。这将阻止此响应的有条件重新验证。
我不太清楚查询的意图是什么，但是 ignore_unmapped 看起来只有 geo distance sorting 支持。
与其他字段排序，unmapped_type property can be used。我认为您正在寻找类似以下的内容
private static void Main()
{
var pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));
var defaultIndex = "posts";
var settings = new ConnectionSettings(pool)
.DefaultIndex(defaultIndex);
var client = new ElasticClient(settings);
var sortType = "asc";
var sortColumn = "TimeReal";
var response = client.Search<Post>(s => s
.Sort(sortFieldDescriptor =>
{
// TODO: probably cache/source generate the mapping of PropertyInfo -> FieldType
var property = typeof(BaseIndexerObject).GetProperty(sortColumn);
FieldType? unmappedType = null;
switch (property.PropertyType.FullName)
{
case "System.Int32":
unmappedType = FieldType.Integer;
break;
// TODO: fill in other relevant Type -> FieldType mappings
}
sortFieldDescriptor.Field(f => f
.Field(sortColumn)
.UnmappedType(unmappedType)
.Order(sortType == "asc" ? SortOrder.Ascending : SortOrder.Descending)
);
return sortFieldDescriptor;
})
);
}
public class BaseIndexerObject
{
public int TimeReal { get; set; }
}
生成查询
POST http://localhost:9200/posts/_search?pretty=true&typed_keys=true
{
"sort": [
{
"TimeReal": {
"unmapped_type": "integer",
"order": "asc"
}
}
]
}
(顺便说一句，我会看一下用于生成查询的代码。生成的内容中有很多多余的 match_all 查询，这会使查询解析不必要地复杂化服务器).
