Hi all, we have a field that contains hostnames like "[foo.bar.com](http://foo.bar.com)". I noticed that when I searched for hostnames with only digits, I got too many results. Let's say I search for "[1234.example.com](http://1234.example.com)", I would also get back all results for [example.com](http://example.com). But this didnt happen if the subdomain is alpha, like [foo.example.com](http://foo.example.com). The search analyzer defaults to the standard analyzer, which tells me:

```auto
{
  "tokens" : [
    {
      "token" : "1234",
      "start_offset" : 0,
      "end_offset" : 5,
      "type" : "<NUM>",
      "position" : 0
    },
    {
      "token" : "example.com",
      "start_offset" : 6,
      "end_offset" : 17,
      "type" : "<ALPHANUM>",
      "position" : 1
    }
  ]
}

```

This seems logical, but then I noticed the type for the second token is ALPHANUM, and surely 1234 is also ALPHANUM and so is the whole [1234.example.com](http://1234.example.com). So why did it get split into 2 tokens?
