Ryan McKinley commented on SOLR-303:

For #3, are there SolrJ parts (or future parts) that we wouldn't want automatically bundled
with Solr?

I don't think so.  The thing I want to make sure is still possible is that solrj can be distributed
independently (without the lucene dependencies)

The existing artifact topology makes sense as is: common, solrj, core.  

Currently we have:
{code}
+ common
  + solrj
  + core
{code}
we need
{code}
+ common
  + solrj  
      +core
{code}
or
{code}
+ common & solrj  
  + core
{code}

This issue is essentially independent of SOLR-303, but we should try to make our source directory
structures consistent with standard practice.

Saving an if() doesn't seem too compelling (the current code could certainly be refactored
to be cleaner anyway). Are there other benefits to having a separate DistributedSearchHandler
though?

If there is a good reason to keep it the *same* handler then that is a reason enough.  

I just looked at it  (without really grocking how it works) and it seemed a bit bloated with
distribution lifecycle stuff.  As long as the non-distributed request cycle isn't tied to
the distributed stuff, I'm sure it is fine.

BTW, where does the term "shard" come from?  What specifically does it refer to?
