Search does not find anything unless "old:" prefix is used
After an out-of-place upgrade to Pega 7, search is not working. However, if "old:" is added as prefix it is working.
Steps to Reproduce
Search for any rule known to exist in the rule base
The root cause of this problem is software user/operation error. The search system settings were not transfered correctly after upgrade.
Correcting the Search and Indexing settings corrected this issue.
