Hi mates,

I am trying to create mapping in my auto completion scenario.

As shown below, I am using "copy\_to" command in order to copy a field value  
into a completion type which name is "factContent\_suggest".

The problem I have encountered is that I cannot update weight property by  
using "factContent\_suggest.weight".  
When I delete this statement, all suggestions come with default weight 1.0.

Thanks for your cooperation.

[http://localhost:9200/factindex/fact/\_mapping](http://localhost:9200/factindex/fact/_mapping)

{  
"fact" : {  
"properties" : {  
"factContent" : {"type" : "string","copy\_to" :  
"factContent\_suggest"},  
"ranking" : {"type" : "long","copy\_to":  
"factContent\_suggest.weight"},  
"factContent\_suggest" : {"type" : "completion","payloads" : true  
}

```
    }
}

```

}
