Cannot create index pattern using alias

Elastic Stack Kibana
1

I added alias in my index.
GET _aliases

...
  "something-2018-02": {
    "aliases": {
      "alias-12index": {},
      "alias-1index": {},
      "alias-2index": {}
    }
  },
...

In Management -> Index Patterns page -> Create index pattern, it tells me there is only one single index something-2018-02. I think I can add an index pattern like alias-1index, alias-*, or do I miss anything?

I try to input alias-* in the textfield, but the Next step button is disabled and I am not able to create index pattern.
