Hi,

I have indexed my Asset collection using command like this:

# Create river for Asset collection

[http://localhost:9200/\_river/asset\_river/\_meta](http://localhost:9200/_river/asset_river/_meta) -d '{

"type": "mongodb",

"mongodb": {

```
 "db": "my_database",

 "collection": "Asset"

```

},

"index": {

```
 "name": "asset_index",

 "type": "Asset"

```

}

}'

I think that indexes all columns of every document in the whole collection.  
Does it make sense to index the whole collection – because if I understand  
well this will create as many indexes as columns in the entire collections  
and it might be pretty slow to retrieve the data?

Regards,  
Janusz
