在ElasticSearch Nest C＃中查询内部记录

Question

I have structure like this:

public class OuterResource
{
    public int Id { get; set; }

    [Nested]
    public List<InnerResource> InnerResources { get; set; }
}

public class InnerResource
{
    public int Id { get; set; }
    public int OuterResourceId { get; set; }
    public int Value { get; set; }
}

Inner records are stored as lists inside outer records. I want to query inner records, giving specified outer resource id and value to filter inner records.

How to do it in C# Nest? Can't figure it out from documentation.

Answer 1

请尝试这个。

    objforOuterResource.InnerResources.Where(x => x.Id == 5);

Answer 2

.Query<OuterResource>.Nested(n => n
    .Path(p => p.InnerResources)
    .Query(qq => qq
    .Terms(t => t.Fields(fi => fi.InnerResources.First().OuterResourceId ).Terms(value))
    )
)

Should work. Note the .First is applied to all the array (=list)
