While I wait for Splunk support to get back to me on my case, I'll pose the problem here.
After moving DB folders back into Thaweddb, I completed the needed steps from the 6.3.4 documentation to rebuild and restart the indexer.
http://docs.splunk.com/Documentation/Splunk/6.3.4/Indexer/Restorearchiveddata
Unfortunately, the events are still not searchable. What else can I try to get the events searchable?
After trolling through more backup files, I found a hot bucket related to the warm bucket that I previous had. Not at much data, but it will help.
I found this GEM - https://answers.splunk.com/answers/13032/is-there-a-way-to-restore-hot-buckets.html
The only thing I can think of is the warm bucket is corrupt.
