Search not updating after moving managed metadata term under new parent term

Question

I have issue where moving metadata term isn't reflected to search.

1. I have simple hierarchy of metadata with two parent terms A and B, and A has one child term C.
2. On some SharePoint list item with managed metadata field called MyCategory, I assign C as the metadata value.
3. Run full crawl
4. Search for items containing the term, e.g., k=owstaxIdMyCategory:[GUID] where [GUID] represents ID of term A --> I get all items tagged with term A and term C
5. I move term C under B
6. Run full crawl
7. Run Taxonomy Update Scheduler timer job
8. Search for items containing the term, e.g., k=owstaxIdMyCategory:[GUID] where [GUID] represents ID of term B --> I get all items tagged with term B but not the item tagged with term C
9. BONUS: Search for items containing the term, e.g., k=owstaxIdMyCategory:[GUID] where [GUID] represents ID of term A --> I get all items tagged with term A and still the item tagged with term C

How to reflect this change in managed metadata term structure in search as full crawl and running Taxonomy Update Scheduler don't help?

Running Index Reset seems to do the trick. Feel free to comment if you know lighter way.
