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
