[TYPO3-Solr] File-Indexing with Solr and Tika

[msh2 at gmx.net]

Hi,
 
I’m using TYPO3 v4.5.29 and installed the Solr-extension v2.8.3 wich is successfully connected to Solr-Server. Additionally I installed the tika-extension  (v1.2.0) configured to use the local JAR.  There are no errors in TYPO3-reports tool and indexing of pages works fine.
 
But now my problem is that linked files (links in RTE of content elements to pdfs in fileadmin) are not added to the index. I’ve searched in web about this topic but can’t figure out how to set up the right configuration.  My typoscript-configuration according to solr:
 
plugin.tx_solr.enabled = 1
plugin.tx_solr.index.enablePageIndexing = 1
plugin.tx_solr.index.enableFileIndexing = 1
plugin.tx_solr.index.files.allowedTypes = pdf
 
Could you please give me some advice?
