<code>cd /opt/lucidworks-hdpsearch/solr/bin/./solr -e dih
This line does not work, can you update the content?
I agree, this should be reported as a doc bug. I think what is meant here is
./solr -e dih (-e flag means start an example. In this case ExtractingRequestHandler example is probably started when you say "-e dih". I have not tested this myself but that's what I can guess looking at the instructions)
