how ILM evaluates indices that have been reindexed recently due to mapping change?  
Does reindex modify the age of indices from ILM perspective so ILM is impacted?

for instance

- I set ILM to "Delete 30days from rollover".
- I reindex all indices
- is 29old index deleted next day, or I will have to wait 30days to delete all indices reindexed that day

thank you
