We store user interaction with application in Elasticsearch. Data is in following format:

```
{ 
  "header": {
        "timestamp": "2016-07-16T19:20:30.45+01:00",
        "sessionID": "ABAD1D"
  },
  "body": {
        "menuTag": "homepage"
  }
}

```

We would like, for some date, to extract application flow. For example:  
{  
"from": "homepage",  
"to": "otherPage",  
"number": 563  
}  
We use sessionID to track current user. Is there a good aggregation that can help us?
