setWindowFields for rank aggregations makes filtering extremely slow

Working with Data

Hello,

I’m currently building an aggregation pipeline to get a rank of a user based on a certain property.
The pipeline looks as follows:

[
  {
    $setWindowFields:
      /**
       * query: The query in MQL.
       */
      {
        sortBy: {
          kills: -1,
        },
        output: {
          denseRankQuantityForState: {
            $denseRank: {},
          },
        },
      },
  },
  {
    $project:
      {
        _id: "$_id",
        type: "$type",
        xuid: "$xuid",
        kills: "$kills",
        rank: "$denseRankQuantityForState",
      },
  },
  {
    $match:
      {
        xuid: "my_xuid",
        type: 0,
      },
  },
]

There are indexes for type, xuid and type + xuid as a compound index.

It seems though that MongoDB is not able to leverage any of these indexes in the final matching step. Since that collection has over 4 million document entries, the query is way too slow (it exceeds the normal execution time limit.

Is there anything I can do to tell MongoDB to use one of my indexes?
