I've created a class com.thomas.ObjectSearchScript that extends  
AbstractFloatSearchScript. The documentation on native scripting  
isn't too clear to me. I assume creating a jar containing just my  
class and placing it into the lib directory will load the class. How  
do I actually register it through settings or in a plugin using  
ScriptModule?

I'd like to eventually be able to use my class by issuing the  
following query:

{  
"query":{  
"custom\_score":{  
"query":{  
"query\_string":{  
"default\_field":"title",  
"query":"grand theft auto"  
}  
},  
"lang":"native",  
"script":"ObjectSearchScript "  
}  
}  
}

Did you try to give in the query the full classname ? With the package ?

Hope this helps

Sorry wrong answer :  
Did you put your script in settings ?

Registering them can either be done by settings, for example: script.native.my.type set tosample.MyNativeScriptFactory will register a script named my.

I tried that out but the native script cannot be found when issuing  
the query. Here's how I modified my settings:

curl -XPUT '[http://localhost/media/\_settings](http://localhost/media/_settings)' -d '{ "index" :  
{ "script.native.my.type" : "com.thomas.ObjectSearchScript" } }'

Here are what my settings look like after modifying them:

{"media":{"settings":  
{"index.number\_of\_replicas":"1","index.number\_of\_shards":"1","index.index":"media","index.script.native.my.type":"com.thomas.ObjectSearchScript"}}}

Here is my query:

{  
"query":{  
"custom\_score":{  
"query":{  
"query\_string":{  
"default\_field":"title",  
"query":"grand theft auto"  
}  
},  
"lang":"native",  
"script":"my "  
}  
}

BTW, I also created a plugins directory under $ES\_HOME and copied my  
jar to the directory in addition to $ES\_HOME/lib.

It seems that you have a blank after "my" here :  
"lang":"native",  
"script":"my "

Try to remove the blank.

Hope this helps

I tried that out but the native script cannot be found when issuing  
the query. Here's how I modified my settings:

curl -XPUT '[http://localhost/media/\_settings](http://localhost/media/_settings)' -d '{ "index" :  
{ "script.native.my.type" : "com.thomas.ObjectSearchScript" } }'

Here are what my settings look like after modifying them:

{"media":{"settings":  
{"index.number\_of\_replicas":"1","index.number\_of\_shards":"1","index.index":"  
media","index.script.native.my.type":"com.thomas.ObjectSearchScript"}}}

Here is my query:

{  
"query":{  
"custom\_score":{  
"query":{  
"query\_string":{  
"default\_field":"title",  
"query":"grand theft auto"  
}  
},  
"lang":"native",  
"script":"my "  
}  
}

jar to the directory in addition to $ES\_HOME/lib.
