How to index asset files with Solr

If you want to index file contents (PDF files for example), you’ll need a parser software named Tika. This software will extract searchable content from a file and pass it to Solr for indexing.

Using Tika in Drupal

To use Tika in Drupal, you need the “Apache Solr Attachments” module. Configure it as follows:

  • Extract using: “Tika (local java application)”
  • Tika directory path: “/usr/local/bin”
  • Tika jar file: “tika.jar”
