Solr Search Context

I am using CF10 and Solr search, sometimes teh context has no values and makes it difficult to explain why a result ranks so high.

I found this

http://help.adobe.com/en_US/ColdFusion/10.0/Developing/WSe9cbe5cf46252 3a0-5bf1c839123792503fa-8000.html

which explains how to make the necessary changes.

However, there is no 'conf' directory in my C:\ColdFusion10\cfusion\collections directory

Should I be updating in C:\ColdFusion10\cfusion\jetty\solr\conf ?

Some other location?

I need this to be a general fix applied to all current and future collections

Thanks
