Evaluate more than one index format

[sol-malisani]

In my AWS Open Search cluster I have diverse index formats, such as:

• xxxxx-2021.09.09 (%Y.%m.%d index format)
• xxxxx-2021-08-11 (%Y-%m-%d index format)

Will be great if the lambda could evaluate different index formats simultaneously, i.o index_format = [ %Y.%m.%d, %Y-%m-%d, .... ]
