Refer to Fig A below. (Also attaching the image as attachment to this thread) This way Oracle WCS trying to replace Lucene with Solr. I would like to achieve Fig B. Identify the Lucene configuration in solr. Make Oracle WCS use the Lucene used in Solr. I want to understand on how this can be achieved, I will be creating a subclass to com.fatwire.search.lucene.LuceneSearchEngine and use this subclass in the configuration table (SearchEngineMetaDataConfig table).
I want to override the relevant methods of the subclass, such that it points to the Lucene in Solr. I need help on how I can point my subclass method to point to Lucene in Solr.
I am using WCS 12c with Solr 4.2.0 (Solr deployed to the tomcat/weblogic container as webapp)
Please help with your pointers.

Thanks
