Question

我正在使用 v10 SDK (Microsoft.Azure.Search) 来构建技能集。我有一个索引，其中包含一个定义为 Edm.Double 集合的货币字段。这将保存文档中的所有货币价值。

当有货币价值时，一切正常。

当文档中没有货币值时，该值将为空并且输出映射给出警告：

<块引用>

无法将输出字段“钱”映射到搜索索引。检查索引器的“outputFieldMappings”属性。

这只是一个警告，但它确实填满了日志;-)

这是我尝试默认值的 C# 代码（以下示例 2 here）

_skillset.Skills.Add(new ConditionalSkill {
  Context = "/document/pages/*",
  Inputs = new List<InputFieldMappingEntry> {
    new InputFieldMappingEntry("condition", "= $(/document/pages/*/output_money) == null"),
    new InputFieldMappingEntry("whenTrue", "= []"),
    new InputFieldMappingEntry("whenFalse", "/document/pages/*/output_money"),
  },
  Outputs = new List<OutputFieldMappingEntry> {
    new OutputFieldMappingEntry("output", "money")
  }
});

当我尝试这个时，我得到一个错误：

Microsoft.Rest.Azure.CloudException: One or more skills are invalid. Details: Input 'whenTrue' source is an invalid expression (= []): Parsing failure: unexpected 
'['; expected ConditionalLevel (Line 1, Column 3); recently consumed: =

在 Azure 认知搜索技能集中，我可以为集合 (Edm.Double) 设置默认值吗？
