Hello!

Is there way to pass parameter to native script? For example, if I  
execute query

{  
"query": {  
"custom\_score": {  
"query": { ... },  
"params" : { "x" : "value" },  
"lang":"native",  
"script":"CustomScript"  
}  
}  
}

- how do I access value of "x" parameter in the native script  
CustomScript?

Thanks!

via params:

public ExecutableScript newScript(final Map\<String, Object\> params) {  
return new AbstractFloatSearchScript() {

```
        @Override
        public float runAsFloat() {
            params.get("xy");

```

....  
}}}

Hi.  
I have a doubt about this.  
Exactly where are we suppose to write this function.  
I mean as we are returning AbstractFloatSearchScript I wrote this  
function as a part of factory class.  
Does this means class returned by my factory is nested class?  
I didn't write Script.class at all.  
My factory class is at [https://gist.github.com/1073346](https://gist.github.com/1073346).  
Is there any mistake, because I am getting this error continously  
git://gist.github.com/1073348.git.  
Can anybody help me to where to include this function?

It can be an inner class, or another class defined, it does not matter. Can you post your config based on the same code you provided?

My Config file.  
script.native.foo.type:  
in.vedantu.search.scripts.SampleScriptFactory.

Actually I am able to access params in newScript function of  
SampleScriptFactory.  
But if I don't create SampleScript.java, then I get error I mentioned  
earlier.  
If I create SampleSctipt.java then I can't access params.
