I ran the command bin/nutch crawl urls -dir crawl -depth 3 >& crawl.log
When I viewed crawl.log I found some errors such as: Can't retrieve Tika parser for mime-typeapplication/x-shockwave-flash, and some other similar messages for other types such as application/xml, etc. Do I need to download Tika for these errors to go away? Where can I download Tika so that it can work with Nutch? If there are instructions to install Tika to work with Nutch please send them to me. Thanks, Roger
