Read about how to use an existing Lucene index in Solr at the solr-user mailinglist. Hopefully that helps!

Hi Mats,

My application already has the Lucene´s indexes and I want to use it with the Solr passing the path where the indexes are stored. How can I do this?

Thanks a lot.
André

The exception indicates that the request timed out while trying to get results from the Solr server. This can be caused by the Solr server not being available, locking up or other issues. Try issuing the same query through the web interface to the solr server or use Wireshark to look at the traffic between your application and the Solr server.

I am trying to run a SolrJ test program. I am having problems with the Tomcat 6.0 configuration for SolrJ. Sorry for posting the Exception Trace. What does it mean:

A very helpful tutorial, thanks!

BTW, I think this line should be tweaked:
List facetEntries = facet.getValues();

To:
List facetEntries = facet.getValues();

At least with my compiler setup I was getting a warning about missing semicolon in the first version.

@Sergey: Remember to commit after adding the documents, otherwise they will not be added to the index.

@aida: To index xml-files directly, just submit the XML documents through a regular POST operation to the /update-handler. This is what solrj does in the background for you.

Very helpful tutorial!

Trying to follow it, I wrote a small app that uses Solr through Solrj. Everything works fine except for the fact that I don’t get the results I expect. :) Probably because I can’t find where the indexed data is kept. The Solr documentation says that it should go the the solr/data directory which is made automatically by Solr. But it’s not there.

Does anybody know the answer?

Thanks a lot.

Hi All,

I want to index the document fields in a xml file to index using solrj. I
know how to index the document fields using doc.addfield(). But I dont know
how to post the xml document instead of adding each field in solrj.

Can I index xml file using solrj? Can anyone help me in how to do this?

Thanks,
