Hi,  
I have this mapping:

products: {  
product: {  
boosts: {  
properties: {  
isAvailable: { type: "boolean" }  
}  
}  
}

And while doing this query:  
{  
"from": 0,  
"size": 20,  
"query": {  
"custom\_score": {  
"script": "\_score \* (doc['boosts.isAvailable'].value ? 1 : downBoostFactor)",  
"params": {  
"downBoostFactor": 0.001  
},  
"query": {  
"match\_all": {

```
			}
		}
	}
}

```

}  
I get error saying: nested: ScriptRuntimeException[expected Boolean; but found: java.lang.String];

Am I doing something wrong? Can boolean fileds be queried in script?

Thanks
