在多个字段上排序 [英] Sorting on Multiple Fields

问题描述

Nest支持在多个字段上排序吗?例如，假设我要首先按FieldA升序排序，然后按FieldB降序排序.

Does Nest support sorting on multiple fields? For example, say I want to sort first by FieldA ascending and then by FieldB descending.

我当前的方法如下:

searchDescriptor.Sort(s =>s.OnField("FieldA").Ascending().OnField("FieldB").Descending());

但是"FieldB" .Descending()部分似乎是发送给elasticsearch的唯一排序选项.

But the "FieldB".Descending() part seems to be the only sort option that is sent to elasticsearch.

有人知道是否还有另一种方法可以做到这一点?

Does anyone know if there is another way to accomplish this?

推荐答案

您正在同一排序描述符上添加多个字段，这将覆盖先前的值.相反，您需要为每个字段指定一个新的排序描述符:

You are adding multiple fields on the same sort descriptor, which is overriding the previous value. Instead, you need to specify a new sort descriptor for each field:

searchDescriptor
    .Sort(s => s
        .OnField("FieldA")
        .Ascending()
    )
    .Sort(s => s
        .OnField("FieldB")
        .Descending()
    )
