[Zope] ZCatalog, SQL database and PDF files

Did anyone have done something like that successfully? To people like me, a
How-To is needed seriously!

Also, one more question for combining ZCatalog and SQL Database searching --
do I really need to index the data in the SQL database into the ZCatalog
when they are already indexed in the SQL database? Can I somehow link the
ZCatalog to a SQL search interface so that when I search a ZCatalog, it will
trigger the SQL search, and at the end combine the result into one report?
Or, am I making it more complicated than it should be?
