Swish parses the Info dictionary of the pdf file using the program
pdfinfo.  Newlines are allowed in the Info tags -- but I'm not clear
how pdfinfo deals with them as I don't have any pdf docs with
newlines in the tags that I know of.  Swish assume they will be
printed by pdfinfo as single lines.

If you have a multi-line pdf info tag then run pdfinfo on the file and
post back what it reports.  It will be easy for you to adjust the
filter, if needed.

The info tags are just placed in html <meta> tags.  How swish indexes
or doesn't index them is up to the swish-e config file.

Sorry, the mailing list software we have doesn't allow attachments.
