ElasticSearch (Nest) and grouping

Elastic Stack Elasticsearch
1

Hi guys,

We have an index in ElasticSearch whose root document includes a property
called Type. Type can have one of the following values:

"Track", "Video","Ringtone".

We want to query the index, and return all documents whose Title property
includes "Micheal". However, we want exactly 10 documents of each Type in
the result set. For example 10 Tracks, 10 Videos and 10 Ringtones whose
Title property includes "Michael".

I am using Nest. How can I do this grouping?

There are currently two options:

  • Run 3 queries - I'd recommend this approach using the multi-search
    interface
  • Request a large number of results and group client side

Baked in grouping support is lacking:
Field Collapsing/Combining · Issue #256 · elastic/elasticsearch · GitHub ( don't +1 the
issue, it has enough :slight_smile: )

Thanks,
Paul

I have almost stopped linking to issues because of the +1s. :slight_smile:
