Hi everyone,  
I was wondering if when I use a bool/filter there is a default sorting. For example, I wrote this query:

```
POST myindex/_search
{ 
  "query": {
    "bool": {
      "filter": [{
        "match_phrase_prefix":{ "MyField" : "sa" }
    	        }]
    		}
    	}
    }

```

and it seems that the results are ordered by \_version value. Is it just coincidence?  
Thanks.
