Enabling scripting for installed scripts only

Hi,

We'd like to enable custom scoring using a script that we'll install under
config/scripts, so that we can invoke it as part of a function_score query,
like

"query": {
"function_score": {
"query" : { ... },
"functions": [ {
"script_score": {
"script": "my-script" // installed in config/scripts/my-script.mvel
}
}]
}
}

In order to do this, it looks like we have to set

script.disable_dynamic: false

in elasticsearch.yml.

But that also allows arbitrary script code to be submitted as the body of
the script field, which we want to disallow.

Is it possible to configure scripting to work only with named scripts that
are installed? It seems like the one config option I found is to coarse
for this.

Thanks!

Hey,

I just tested with 1.2.1, and even if dynamic scripting is disabled, you
can still execute locally stored scripts. See the example in

You're right. Was sure I tried that, but obviously had done something
wrong along the way.

Thanks!
