autocommit is really the right answer here for the discussions going
on today. When there are multiple streams of incoming documents to
Solr, unless you want to build some kind of coordinated system that'll
control commits, simply use autocommit. Definitely a commit-per-doc
is not recommended, and highly discouraged.
As for indexing - it really is the more the merrier, to a point.
Server RAM is needed to handle incoming requests, and these rich
documents are typically large'ish. Throttling so as to not add too
many (how many is that? gotta test with your system and RAM and
solrconfig.xml settings) docs at a time is going to be needed in some
way.

I did in fact try setting commit in the Solr output connection

on occasion due to overlapping requests - one request did a commit
while other parallel requests from LCF were in various stages of
processing. I do not recall whether I tried to set JVM throttling to
1 to force sequential processing of posted documents, but you don't
really want to have to force sequential processing anyway.
Side note to Solr guys: What is the "contract" for the
ExtractingRequestHandler in terms of handling parallel requests? Is
it "the more the merrier" (including lots of PDF files?), or are
there specific issues that the client must/should worry about? There
is also the potential for multiple clients, LCF or other,
simultaneously blasting at /update/extract. Obviously those clients
can't know what each other is up to.

You can send any argument you want by configuring the output
connector. However, the explicit commit on every post will slow
down performance of your crawls.

Hi,
Yes that is where I was stuck up.. making an explicit commit..
Can I send the argument commit=true while configuring the Repo
connector.
Thanks & Regards,

A short Solr tutorial is here:
http://lucene.apache.org/solr/tutorial.html
After running an LCF job that uses a Solr output connection, be sure
to manually force a Solr "commit", for example:
cd .../apache-solr-1.4.0/example/exampledocs
java -jar post.jar

Hi,
I am stuck at setting up the Solr server to be used with LCF.
I am new to Solr.
