hello,
my elasticsearch has more than 500 indices and each index has many fields. i wonder if there is a API/query to check a specific field name belong to which indices. e.g. "abc" field belongs to which index.
i guess i can find this via index _mapping result, but i am using dynamic mapping which creates indices daily basis and my elasticsearch stores up to 90days, so it is not really good for me and would understand better way.
please advise.
thanks!
