I want to add all the arguments for my event to be indexed

event TokenPurchase(
  address indexed purchaser, 
  address indexed beneficiary,
  uint256 indexed value,
  uint256 indexed amount,
  uint256 indexed refund_amount
);

But im getting this error when i compile

TypeError: More than 3 indexed arguments for event.

Am I really limited to three items indexed?

From the docs:

Up to three parameters can receive the attribute indexed which will cause the respective arguments to be searched for: It is possible to filter for specific values of indexed arguments in the user interface.
