Filtered queries aren't working

I've got a Quickslice instance running and I've confirmed 1) regular queries work, and 2) there is a record that should be returned by this filtered query. Non-filtered queries seem to work fine, but as soon as I apply a filter I get no results. I'd be happy to find out that there's something wrong with my queries, but they're adapted directly from the docs site so I'm pretty confident in them.

Non-filtered query

query {
  gamesGamesgamesgamesgamesGame {
    edges {
      node {
        name
      }
    }
  }
}

Response

{
  "data": {
    "gamesGamesgamesgamesgamesGame": {
      "edges": [
        {
          "node": { "name": "asdf" }
        }
      ]
    }
  }
}

Filtered query

query {
  gamesGamesgamesgamesgamesGame(where: { name: { eq: "asdf" } }) {
    edges {
      node {
        name
      }
    }
  }
}

Response

{
  "data": {
    "gamesGamesgamesgamesgamesGame": {
      "edges": []
    }
  }
}
