The current Do Search operation is apparently limited to the fields of its data type and cannot deal with indirect fields, from other but related data types.
For example, when considering the following:
1 - a repeating group is of A type
2 - data type ‘A’ has one of its field ‘b’ of B data type
3 - data type ‘B’ has one field ‘c’
It sounds like there is no way to pouplate the repeating group through a Do Search on A.b.c. It would be very helpful to offer this capability, if possible not limited to only one indirection. I understand that circular dependencies could be a bit tricky to detect and reject.
