Here is the contents of my sitemap.txt
http://www.merrittnet.org/Papers/
http://www.merrittnet.org/Marmot/
in these 2 directories are around 50 PDF files it has been around 5 days now and when I search using
https://cse.google.com/cse?cx=acf88dbf364fe0f82
(search words like "water" or "hydrology" should return some hits but dont or FileType:pdf)
Is there some special configuration that needs to be done for a folder of PDFs
also to note in these directories I have an index.php that dynamically creates href links for all.pdf files in that directory.
