Yes, general@lucene is the main point of contact for people interested in
the *entire* Lucene project -- either because they want to discuss the
organization of the project, propose new subprojects, or have questions
about search related technologies but have no idea where to start (Solr?
Nutch? Lucene-Java? etc...)
: I see subscribing users constantly redirected to java-user, because
: there is much greater traffic over there.
while it's true the traffic on java-user is greater, that is really a
secondary issue. People get refered to java-user when they are asking
questions about using the Java API. When people ask questions like "How
can i make nutch only crawl one site?" they get refered to the nutch-user
Since a large number of people associate "Lucene" with only the java API,
there tend to be more people posting Java API questions on general@ then
there are people posting Nutch questions, but the principle is the same.
