Hi,

Is there a way to categorize similar values of specific field, during the query time ?

for example, suppose I have these documents:

1. {..., message: "this is message no 1",...}
2. {..., message: "this is message no 2",...}
3. {..., message: "the message: 'very long message' is too long",...}

my goal is to aggregate the message not by term, but by pattern, so for the given example I expect the result to be something like this, not necessarily the exact same:

```
{
    buckets: [
      {
        key: 'message: "this is message no 1"',
        pattern: ''this is message no"
      },
      {
        key: 'message: "the message: 'very long message' is too long"',
        pattern: 'the message: is too long'
      }
    ]
  }
```
