Hi Shairon,
You're talking about the param mapping for querying? What version are
you using?
The most recent changes to RSolr have involved stripping out all of
the param mapping and response helpers. It's now a very simple and
pure client lib, which was my original goal.
The param mapping and response helpers are now in a different library
called rsolr-ext:

This library (rsolr-ext) is going through some major changes right
now. I hope to have some good stuff up by the end of the week.
