How to search Contacts by Event fields like birthday or anniversary using ionic-native


How can we search the contacts by event (date) e.g. Birthday or Anniversary or any custom event?
The current filter in Contacts.find() method takes only string. And therefore, the only possibility I see as list down all the contacts, iterate over them and filter by matching the event date values.
Please let me know if there’s any other better way.

Thanks in advance!
