Velocity to fetch full docs?
Hi,
I am using Nutch/Solr to index an intranet of about 12 million pages and
when I do a search I want Solr to retrieve the full documents and append
them into a single simple HTML doc (no js, not ads, etc.), then shoot the
single doc to another (nonSolr) process for postprocessing. Can I use
Velocity to do this? How? Can Velocity "reach back" to the Nutch crawl for
the full text of the docs (they don't change often at all)?
Any help would be much appreciated.

Indeed, Velocity is a very simple template engine, with no smart APIs
provided by the engine alone. What you need to do is to put in the
context some data objects holding the instance data you're currently
processing (or even just the servlet request and response objects to get
access to the request parameters), and some smart objects that can
contact Solr, Nutch and your other nonSolr services. You'd have to write
these yourself in Java, and put instances in the velocity context before
parsing.
Another approach is to put enough low level services to allow you to
implement the whole logic inside a Velocity template, like a HTTP
client, XML processing library, the escape tool, etc.

Definitely for a question for the Nutch or Solr lists. Velocity is a
simple template engine and knows nothing about Nutch or Solr that it
isn't "told" about.
