[Lists] Count top-level documents instead of nested documents when using nestedField
Affected Projects React / All
Is your feature request related to a problem? Please describe. Nested fields count is based on nested documents. Would be great to have a way to switch it to count on the top-level document. This would apply to all lists with a count.
Example:
bookshelf1.books : [
{ book1: {author: "John Doe} },
{ book2: {author: "Rick Doe} },
{ book3: {author: "John Doe} },
],
bookshelf2.books : [
{ book1: {author: "Jane Doe} },
{ book2: {author: "Jane Doe} },
{ book3: {author: "John Doe} },
]
Currently, if filtering on bookshelf.books.author, one would get the following counts on "books":
John Doe 3
Jane Doe 2
Rick Doe 1
would be great to be able to switch to a count on "bookshelf":
John Doe 2
Jane Doe 1
Rick Doe 1
Ultimately, the results returns (unless using inner_hits) are based on the top-level document (bookshelf) in this example. Therefore, I think it feels more natural to display the count on them in many cases.
Describe the solution you'd like
One way would be to add a boolean prop e.g reverseNestedCount which would then change the aggregation method. To my knowledge there is currently no way to modify the aggregation used for counting but I could be wrong (?).
In ES, this would be achieved using a reverse nested aggregation.
Describe alternatives you've considered I guess the alternative would be to write a component from scratch
