Alias filter and duplicate attributes in different mappings

Hi,

In version 1.7.3 of Elasticsearch, he had two mappings with three equal fields (Field1, Field2, Field3), and those areas were the default alias filtering.

PUT / INDEX / _alias / ALIAS
{
 "Filter": {
               "And": {
                  "Filters": [
                     {
                        "Term": {
                           "Field1": 2
                        }
                     },
                     {
                        "Term": {
                           "Field2": 1
                        }
                     },
                     {
                        "Term": {
                           "Field3": 1
                        }
                     }
                  ]
               }
}
}

When you upgrade to version 2.0 of Elasticsearch, and I can not be duplicated on different mapping attributes, so no longer the same name, and I can not put the filter level alias.

Do I have to have two types of aliases for each filter you want to apply? Or I can have a condition "or" in the filter level alias?

Thank you very much for your help, greetings.
