Event Search not searching through "linked place" text

Can you tell me how to get the event text search area to search the names of the event linked places/CPT?

For example, on our events page: https://vacationokoboji.com/events/ – search for “Barefoot Bar” and you only get 3 results. We have the Barefoot Bar linked with a lot more events. (This “place” is a listing in our custom GD Post Type “Attraction”.)

Can you help figure out why is it only showing 3 events, and tell me how do we get it to show all of the events at that linked location when searched?

Thanks in advance for your help
