I have a pretty basic Drupal 7 web site with Solr search (works great!).
I would now like to perform some "work" after each node is indexed with Solr.
First I tried creating a workflow rule but there is no event for "node has been indexed". Next I looked for Solr API hooks but came up empty handed.
Should I look at adding a hook somewhere in the PHP code? If so where? Or am I overlooking a more obvious solution?
