NOTE: Indexing Drupal Content in Islandora Solr's index is not required, but it is a feature some users have requested.

Indexing Islandora Fedora and Drupal Content in the same Solr index allows sites to simplify searching for end users by allowing them to search all content from one search interface. To search across Drupal and Fedora content you will have to modify your solr schema.xml and you will also need to update the Islandora Solr search results to make them aware of Drupal content, there are a couple of ways to modify the results but they will involve some code modifications.

You will also need to install the Drupal Apache Solr module (https://drupal.org/project/apachesolr).  The Drupal Apache Solr module installation says to copy it's Solr configuration files to the Solr configuration directory, Do not do this as you will be overwriting your existing Islandora Solr configuration.  Instead update the existing schema.xml file with the required Drupal fields (it's good practice to backup any files before you edit them if they are not already under a vcs).

This section assumes you already have the Islandora Solr module configured to search Fedora content and Gsearch configured to index Fedora content.  We are also assuming you will continue to use the Islandora Solr module to view the search results.

Modify the Solr schema.xml file

Your schema.xml file will most likely be in /usr/local/fedora/solr/conf of /usr/local/fedora/solr/collection1/conf.  We are assuming you installed Solr using the instructions provided in this guide.  The collection1/conf is for more recent versions of Solr.

Add the text below to the fields section of the schema.xml

XML
<!-- ******** Dynamic fields required for Drupal content to be indexed ******** -->
<!-- Dynamic field definitions. If a field name is not found, dynamicFields
will be used if the name matches any of the patterns.
RESTRICTION: the glob-like pattern in the name attribute must have
a "*" only at the start or the end.
EXAMPLE: name="*_i" will match any field ending in _i (like myid_i, z_i)
Longer patterns will be matched first. if equal size patterns
both match, the first appearing in the schema will be used. -->
