Hi all!
I'm trying to reindex my structure in the next way. I have a lot of indexes like "index1"..."indexN".
I want to create next structure - I have one index with "indexes" name, and a lot of alias to every document inside it. I'm using reindex query to move from one index to another, but while executing it, I have next exception.
