How to get Drupal 7 to search attached PDF and Word documents From what I have read it seems like you have to use Solr to have PDF and Word attachments indexed and returned in a search.  I have Solr working with Drupal but I think I need Tika working on Solr in order to do the document indexing.  There is very little documentation I can find for Tika.  Does anybody know where a good source for this is?  Is there a better/easier way to have search in Drupal index attached documents?
To help you, you've this nice module Apache Solr Attachments. If you download the module you'll have a README.txt that give you some clues how to help you install and configure Tika.
