Hi Remi & Sebastian: Here is the example: http://www.srs.fs.usda.gov/econ/data/forestincentives/greene-etal-sofew2006proc.pdf
When Nutch crawls the above, it doesn't grab the title since there is no title defined in the pdf properties. When the same file was searched in Google, you can see the title - https://www.google.com/#q=http:%2F%2Fwww.srs.fs.usda.gov%2Fecon%2Fdata%2Fforestincentives%2Fgreene-etal-sofew2006proc.pdf Thanks..
