Math date support with index name.

For many of our index, like the one from logstash, it's date based.
So I would like to see if is it possible to have something like for index(appName).
I tried , it's getting 200 OK for mapping response. But there is pop up said authentication error. I guess it's because the response doesn't exactly match the index name.

Start by reproducing the mapping request with a date-math index such as and compare its response with the authentication error described. Done means date-based index names are accepted for index(appName) and the response matches the resolved index name.
