I'm trying to use a preloaded javascript file stored in /config/scripts/test.js

[http://www.elasticsearch.org/guide/reference/query-dsl/custom-score-query.html](http://www.elasticsearch.org/guide/reference/query-dsl/custom-score-query.html)

I'm using the Tire gem for Rails integration.

query do  
custom\_score :params =\> {😛 =\> 5}, :script =\> "test", :lang =\> "js" do string '\* end end

If I use an inline script expression, I can access the parameter p very easily. How do I pass it to the preloaded script test.js?

Thanks!  
George
