When creating indexes and sorting with "normal" queries, it is possible to index/sort on a specific array index (e.g. `foo.0.bar`). I do this because the search results grid in our UI only has room to show the first `foo.bar` result, so it doesn't make sense visually to sort by additional objects which the user can't see. Since the new Atlas Search Sort syntax looks the same, I was hoping to do that with it as well, but it doesn't seem possible. Example: ``` [ { "xyzzy": "xyzzy", "foo": [ { "bar": "A" } ] }, { "xyzzy": "xyzzy", "foo": [ { "bar": "B" }, { "bar": "D" } ] }, { "xyzzy": "xyzzy", "foo": [ { "bar": "C" } ] } ] ``` ``` { index: "myindex", returnStoredSource: true, phrase: { path: "xyzzy", query: "xyzzy" }, sort: { "foo.0.bar": -1 } } ``` See: https://support.mongodb.com/case/01169701
