原因

Due to a change in the issue navigator view, now it's not possible to view the parent key field during the filter search results.

ソリューション

First we need to create a new custom field and then use automation to transfer the parent key value into a custom field from the current parent field. Please check the below steps for your reference.

1. Navigate to Setting -> Issues -> Custom field.
2. Create a custom field of text type (parent key) and include all the project screens as per your requirement.
3. Now, use the automation to populate the value of the parent key field based on the value of the parent field. 
4. Include the parent key field during the filter query search result.
