I have a solr instance running for bespoke data already on Drupal using the solr module. What I would now like to do is to replace core search with solr. The current behaviour is: All content types via drupal native search and 'shopping' content type via solr. The solr index is built offline rather than using the drupal cron, and for drupal native search index for all other content types, i am not able to run the cron as there are millions of nodes from the 'shopping' content type i need to exclude. I thought one way to do this is to run a multi-core Solr but within the *same* drupal site, so that one serves 'shopping' content and the other serves all other content types on Drupal. Any thoughts? Thank you!
