Could be due to the fetch size limit. The URL you gave as an example is 163395 bytes long, whereas the default value in Nutch is
<property> <name>http.content.limit</name> <value>65536</value> <description>The length limit for downloaded content using the http protocol, in bytes. If this value is nonnegative (>=0), content longer than it will be truncated; otherwise, no truncation at all. Do not confuse this setting with the file.content.limit setting. </description> </property> Calling Tika directly on a URL is a good way of checking where the problem comes from e.g. /usr/local/bin/tika-0.7/tika-app/target/tika-app-0.7.jar http://www.egamaster.com/datos/politica_fr.pdf works fine J.
