How can i create a "key" for two searches and combine them to one search with a new column by "key"

[i17065]

Hello community i hope you can help me, I'm new here...
The field "moid" for 'folder' has the same values like the field changeSet.parent.moid for 'VMs'.
I want a new column with changeSet.name from 'folder' in the 'VMs' search where changeSet.parent.moid of 'VMs' and moid of 'folder' should be used as "key" to store the folder name to the VMs.
I have tried many things ("inner join" ect.), but did not get a useful result.
Maybe you can help me with a command.
Thank you in advance!
Greetings Lars

Selected Fields for 'folder':

a index 1 = vmware-inv
a moid 100+ = values
a sourcetype 1 = vmware:inv:hierarchy
a type 1 = folder

index="vmware-inv" sourcetype=vmware:inv:hierarchy
