Can't get trigram search _sorting_ to work to save my life

    read :search do
      argument :q, :string, allow_nil?: false

      # Filter by trigram similarity cutoff
      filter expr(
        fragment(
          "similarity(?, ?) > 0.2",
          name,
          ^arg(:q)
        )
      )

      # Order by trigram similarity (desc) - using calculation
      prepare build(sort: [fragment("similarity(?, ?)", name, ^arg(:q))])
    end

    calculate :similarity, :float,
      expr(
        fragment(
          "similarity(?, ?)",
          name,
          ^arg(:q)
        )
      )
