Subject java.lang.NullPointerException at org.apache.solr.handler.component.QueryComponent.mergeIds(QueryComponent.java:421)
Date Tue, 17 Nov 2009 16:09:56 GMT
Hi there!

I am trying to test the distributed search on 2 servers. I've created simple
application which adds sample documents to 2 different solr servers (version 1.3.0).

While it is possible to search for certain keyphrase on any of these servers,
I am getting weird error when trying to search on both of these servers (like
it was described at http://wiki.apache.org/solr/DistributedSearch)

HTTP ERROR: 500

null

These servers are using the same configuration. What may cause this error?

Thank you in advance.
