[Xapian-discuss] Indexing PDF, DOC etc.

[Florian Beer]

I'm trying to index PDFs that are stored in a MySQL database (blob  
field) using omindex now.
What's the exact call to tell omindex to index a byte stream (passed  
directly from my Python programm) instead of specifying a directory on  
the commandline?

Is this even possible, or would I have to first write the PDF data out  
from the MySQL to a temporary file, let it index (supplying arbitrary  
metadata) and then delete the temp file?
