Consider an index `idx`, with a mapping for a single type `docs`. Consider  
aliases of the format `idx-{ACCOUNT-ID}`, with a term filter and a routing  
value set to the account id, like so:

```auto
$ curl http://0.0.0.0:9200/idx/_aliases?pretty=1
{
  "idx" : {
    "aliases" : {
      "idx-1" : {
        "filter" : {
          "term" : {
            "account_id" : 1
          }
        },
        "index_routing" : 1,
        "search_routing" : 1
      },
      ...
    }
  }
}

```

### Questions

1. When indexing a percolator query, if you do that via an alias, will it  
respect the routing?

```auto
# will the alias routing from idx-1 apply to this operation?
curl -XPUT http://0.0.0.0:9200/idx-1/.percolator/1 -d '{query:..., 
account_id:1}'

```

1. When percolating an existing document from one of those aliases, will  
the routing and term filter from the alias be used when retrieving/checking  
the matching percolator documents?

```auto
# will the alias routing and term filter from idx-1 apply to the 
percolators?
curl http://0.0.0.0:9200/idx-1/docs/123/_percolate

```

Any insight much appreciated.
