Solr indexing on custom tables We are implementing apache solr search in drupal 7.. after installing the module if you run the index, the apache solr is returning results from the drupal tables (nodes,users,taxonomy,content type).
But we have created custom tables (example: product table) where apache solr is not able to index those table data.. how to make it index the custom created tables
There is a patch available for this. Please refer the below link
