Subject Re: Indexing Best Practice
Date Mon, 11 Apr 2011 15:48:30 GMT
If it's of any help I've split the processing of PDF files from the
indexing. I put the PDF content into a text file (but I guess you could load
it into a database) and use that as part of the indexing.  My processing of
the PDF files also compares timestamps on the document and the text file so
that I'm only processing documents that have changed.

I am a newbie so perhaps there's more sophisticated approaches.

Hope that helps.
