I have just started using lang-javascript for calculating a custom score,  
and want to debug the script I have written. I checked out the following  
links:

[https://groups.google.com/forum/#!searchin/elasticsearch/javascript$20log/elasticsearch/NwTjyJ35ZoU/ffEPiJq\_K0QJ](https://groups.google.com/forum/#!searchin/elasticsearch/javascript$20log/elasticsearch/NwTjyJ35ZoU/ffEPiJq_K0QJ)

> > [Redirecting to Google Groups](https://groups.google.com/forum/#!searchin/elasticsearch/javascript$20log/elasticsearch/wwaaWsKZ7Nw/sVpEqV2Mi3YJ)

and searched through elasticsearch documentation but am unable to figure  
out how to log from within the lang-javascript script. Can anyone point to  
any relevant documentation or give an example?

Thanks
