At this time, there isn't a search endpoint for tickets like there is for contacts or companies. Apologies for the inconvenience.
The Tickets API is still relatively new, however, so I wouldn't be surprised if we add this functionality in the future. I'll take note of your request internally.
In the meantime, I recommend:
Upvoting and commenting on this feature request noting your need for API search functionality.
Subscribing to or bookmarking the HubSpot Developer Changelog so that you're notified of new features and breaking changes.
