Sorting on Multiple Fields

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

My current approach looks something like this:

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

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

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

Solution

  • 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()
    )
