Index Data from External Database for Search - Views I have a Drupal 7 view which obtains data from an external database and displays it on the page. I would like to index this external data (read through Views) so that the resulting items can be searched for using Drupal Search. How do I go about doing this?
Like Michiel said Solr is a good option but is complicated to set up.

Another option is to implement a Google search server that can then be integrated with Drupal using the Google Search Appliance module. This is a paid solution but easier to setup.
