I knew about Nutch, but I haven't been able to implement a crawler with it.
Have you done that or
Hello!
I think that really depends on what you want to achieve and what parts
of your current system you would like to reuse. If it is only HTML
processing I would let Nutch and Solr do that. Of course you can
extend Nutch (it has a plugin API) and implement the custom logic you
need as a Nutch
