8.15 - What is the intended method to use the .MatchAll() query?

[TSlump]

Elastic.Clients.Elasticsearch version: 8.15.4

Elasticsearch version: 8.15.4

.NET runtime version: 8.0

Hi, I'm trying to get all docs from my elastic index but I'm having trouble with the .MatchAll query. I had imagined it would look like:

var searchResponse = await this.elasticsearchClient.SearchAsync<Model>(s => s
            .Index(Index)
            .Query(q => q
                .MatchAll()
            )); 

However it's asking for a MatchAllQueryDescriptor, I'm sure what I'm meant to put here...

I have a version working with:

.Query(new MatchAllQuery()

Is this the intended method to create a MatchAll query? Any guidance/docs would be be greatly appreciated, thanks.

Hi @TSlump,

the non descriptor based approach is fine to use.

The descriptor syntax is a bit weird in the 8.x client:

.MatchAll(_ => {})

In the 9.x clients we improved the syntax to allow for just:

.MatchAll()

These changes are going to get backported for 8.19.

Please let me know if that answers your question.
