Search broken when message offset is over 10000

When you search with a Message offset over 10000 you will get this no answer, only the serverlog shows this:
```
2017-03-06T11:00:48.897+01:00 WARN [SearchResource] Unable to execute search: all shards failed
```

Same as when you change multiple times the page back then you get this:


And the serverlog shows this:
```
2017-03-06T11:00:48.897+01:00 WARN [SearchResource] Unable to execute search: all shards failed
```
## Expected Behavior
Get Messages after offset 10000

## Current Behavior
Failes

## Possible Solution
it's not the same as: #2306 because i dont get the ES error, but maybe it helps?

## Steps to Reproduce (for bugs)
1. search in the gui
2. change pages until you get the error
or
1. search with the api
2. get no messages

## Context
we tried to do something like tail -f with the api but when we hit offsett 10000 it dies.
