As far as I have understood (and noticed after indexing) solrfal just 
takes what FAL supplies. You can have a "best of both worlds" situation 
with the extension 'extractor' [1]. This allows FAL to use Tika as a 
metadata extraction service.
Now Tika can automatically extract metadata from files and let solrfal 
use this for indexing.
