RT::Tickets not including merged tickets

Is there any way to override the RT::Tickets SearchBuilder’s default
built-in Limit of main.EffectiveID = main.id? I’m writing a
SearchBuilder script where I would benefit from being able to directly
retrieve tickets that have been merged into other tickets.
