I have a map on ArcGIS field maps that contains a feature class (polygons) and 3 nested tables, which have data related to each polygon. Because there are many records in the tables related to each polygon, My field workers need to be able to search a specific record using the search bar. However, it seems that the search bar only works for records in the feature class, not in the related tables.
The following Screenshots Demonstrate the issue:
1. There is a map with polygons.

2. The polygons have nested tables as seen here (titled Balghar Students)

3. You can clearly see that this table has a record with the name "Benjamin"

4. However, if i type benjamin on the search box, I get a response saying that no item has been found.

I hope this clarifies the issue. Can someone please help? Why is this happening and how to work around it? search settings in the map are enables and set correctly.
