Hi all,

Assume that we have a field with N unique values. Documents are grouped by  
these N unique values.

We want to create a Top Hits aggregation, and create for each bucket  
another Top Hits aggregation. We use the nested / deeper Top Hits  
Aggregation to create groups based on these N unique values.

Question: is this possible in ES?

However, we do not want to sort the keys within an bucket by a field in  
ascending or descending order, but by providing by the list of N unique  
values in an explicit order using a list.  
We do not want to sort it by relevance score based on the main query as  
well.

I guess we can do this sorting on the application side, since the list of N  
unique values will be limited.

Cheers,  
/JZ
