I want to search all the events which user has created or has bookings for that events. I gone through documentation but it didn't helped me.
In your documentation i didn't understood how to use "bookings: Include only events with bookings enabled. Use 'user' to show events a logged in user has booked.1 = yes, 0 = no". Its on http://wp-events-plugin.com/documentation/event-search-attributes/ under Event Attributes.
P.S: How to search/filter events using user id
