Hi Lance
Unfortunately, Sphinx itself only talks directly to databases or XML
files - and Thinking Sphinx doesn't yet support the latter (although
I'd like it to at some point). So, unless you want to store the file
information in the database instead - *and* it's a plain text format -
then I'm afraid Sphinx isn't the solution for you. I know you can
handle files somehow with Ferret, and I'd expect the same of Solr. No
idea about Xapian or others, though.
Sorry I can't be of further help.
