After performing a large migration, I came to realize that our Edge-NGram Tokenizer's max token is too small... Am I able to increase this without reindexing the entire index? Also.. How does increasing max size impact performance/hardware requirements?

```

      "index": {

            }
          },

            }
          }
        },

I answered the first part of my question "can I change it". The answer is yes for whoever reads this in the future.

See last paragraph on [https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-update-settings.html#indices-update-settings](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-update-settings.html#indices-update-settings)

As for my second question that one is still a mystery. I am not certain how analyzers work, so I am not sure if modifying min/max settings has any performance/hardware implications?
