== Aliases

`aliases` shows information about currently configured aliases to indices
including filter and routing infos.

% curl '192.168.56.10:9200/_cat/aliases?v'

alias1 test1 -      -            -
alias3 test1 -      1            1

The output shows that `alias` has configured a filter, and specific routing
configurations in `alias3` and `alias4`. 

If you only want to get information about a single alias, you can specify
the alias in the URL, for example `/_cat/aliases/alias1`.
