Hello,

I try to create a track that works on one index but fails with several indices :

```
  "meta": {
    "short-description": "...",
    "description" : "..."
  },
  "indices": [
    {
      "name": "sa_2016_01_1",
      "types": [
        {
          "name": "search",
          "mapping": "mappings.json"
        }
      ],
      "auto-managed": false
    },
    {
      "name": "sa_2016_02_1",
      "types": [
        {
          "name": "search",
          "mapping": "mappings.json"
        }
      ],
      "auto-managed": false
    }
  ],
  "operations": [
    {
      "name": "match_all_query_search",
      "operation-type": "search",
      "body": {
        "query": {
          "match_all": {}
        }
      }
    }, 
  ...................

```

it gives :

but if :  
"indices": [  
{  
"name": "sa\_2016\_01\_1",  
"types": [  
{  
"name": "search",  
"mapping": "mappings.json"  
}  
],  
"auto-managed": false  
}]

Everything works fine.

Hi @Thomas_Louis,

The problem is that Rally cannot derive which index should be targeted by the query, so you need to add the attribute `"index": "_all"` to the definition of the operation "match\_all\_query\_search" (see [docs](http://esrally.readthedocs.io/en/latest/track.html#search) for more details).

Daniel
