Subject Re: [jira] Commented: (SOLR-567) SolrCore Pluggable

IMO, you are underestimating the difficulty of integrating Ocean with 
Solr's current API's.

Also, Jason has already mentioned that Ocean is much more than just 
realtime search. Adding realtime search to something like solr 1.5 is a 
different goal than possibly integrating the Ocean work that has been 
done / is planned, which seems like a very large scope project and if 
done would certainly seem to merit a 2.0 change in its own right.

Still seems large and nebulous to me at the moment...just like solr 2. 
They go well together in my mind <g>
