The usual external parser scripts make use of pdftotext, which comes with the xpdf package. It only extracts plain text from the PDF documents. I've been meaning to try pdftohtml (http://pdftohtml.sourceforge.net/) but haven't yet had the chance. I don't know if it will extract hypertext links from the PDFs, but it's worth a try. If you do try it, please let us know how it goes. You may want to retrofit this tool into doc2html.pl, so you get all the wrapper script handling of arguments and such. If pdftohtml doesn't do it, I've found the following trick seems to find links in PDFs, but without the description text, so you could try working this into an external converter script: strings file.pdf | sed -n 's|^/URI (\(.*\)).*|<link href="\1">|p' > 2. > Our intranet is sprinkled with links back to the firm directory.

Try lowering the value of the backlink_factor attribute (see http://www.htdig.org/attrs.html#backlink_factor) to see if that helps (no need to reindex). Also, if the word "technology" appears in the link description text for the links to any of the individuals' pages, that will greatly boost their score if description_factor is still at the default value. If that's the case, you can lower this factor too (you'll have to reindex if using the 3.1.x series), or change the descriptions and reindex. -- Gilles R.
