I see many of the fields in my indices have large text data. Because of this after upgrading from 5.x to 7.0 I'm seeing shard failures in kibana.
I found that i can use term_vector for such field in the index mapping.
Is there a way to auto configure mappings such that fields violating max_length are configured as term_vectors?
Is there a way to update mapping with term_vector or the indices have to be reindexed?
