@justinleet Your example suggests that by using a LukeRequest and calling
getFieldInfo() on the result, we should be able to naturally obtain the
filtered list of fields that can be used as a whitelist when constructing the
index update? And it's available since Solr 1.2? This sounds pretty clean to me
and it seems to solve the problem in a general way without exposing Solr
implementation details to the end user (whether by API or documentation).
