filter payments by date and by email in php

I am using the mercadopago.php library and would like to know how to filter payments approved by a specific date and also by payer_email.

• In this way I get the approved payments

$ filters = array (
    "status" = > "approved",
);

$ search_result = $ mp-> search_payment ($ filters, 0.100);
print_r ($ search_result);

• To filter by date I tried the attributes:
  

  
  $ filters = array (
  

  "status" = > "approved",
  "begin_date" = > "2017-12-01T00: 00: 00Z",
  "end_date" = > "2018-01-01T00: 00: 00Z"

  
  )
  
  
  $ search_result = $ mp-> search_payment ($ filters, 0.100);
  print_r ($ search_result);

I took these attributes from an example that the library brings but does not filter by date, the filter keeps getting all the approved payments.
