SolrJ - CommonsHttpSolrServer

[Christopher Gross <co...@gmail.com>]

I have SolrJ working, but it is running slower than I'd like.  The logger
spits out a lot of things that make me feel like I don't have something
configured quite right.  Instead of holding on to the connection, I think
that it closes it each time.  I'd want it to stay open -- I'm trying to do a
clean load of data and I think it would go faster if the connection stayed
alive.

I made a function to create the CommonsHttpSolrServer object, set the
parameters and the parser and set it to the right url, then I use that
object in all of my routines.  I tried to use the SolrServer object in the
wiki, but I need to set the parser and I can't do that unless I set the
HttpClient, but then I'm not using the Solr aspects...right?

Can someone point me to some more in-depth code examples of SolrJ?  Or if
there is a spot that better documents how all this is supposed to work?

Thanks!
