Elasticsearch父/子，FacetDateHistogram使用子数据

Question

我在父/子关系中运行此NEST客户端查询，我需要运行FacetDateHistograms / FacetTerms，使用父数据或使用子父：

这适用于使用父数据的方面

sourceClient.Search<type_properties>(body => body.Query(q => q.Bool(b =>b.Must(q.Term("zip","90064"),q.HasChild<type_sales(x=>x.Query(asofF=>asofF.Range(rangeFrom=>rangeFrom.OnField("salesDate").From("2009-01-01T00:00:00"))))))).FacetTerm("Global Count", gc=> gc.OnField("state").Global().Size(60)) .FacetTerm("Zip Count", zc=>zc.OnField("zip")))

但如果添加此FacetDateHistogram，其中“salesDate”和“salesPrice”是子字段，

.FacetDateHistogram("ZipSales",h=>h.OnField("salesDate").ValueField("salesPrice").Interval(DateInte
                                                rval.Year))

返回

            }
          }
        }
      ]
    }
  }
}]]]

请帮忙吗？
