I cannot get hits back and do not get a correct total number of records when
using shard searching.
I have 2 cores, core0 and core1. Both have the same schema.xml and
solrconfig.xml (different datadirs in solrconfig.xml).
Our id field contains globally unique id's across both cores, but they use
the same id field (same schema.xml).
Issue exists when testing with Jetty and Tomcat. Using Solr 1.4.1.
I found two other instances of this exact error on Google and neither have a
solution, just a description like mine with lots of responses. Multi-core
searching is something we need due to data layout including multiple
languages.

Notice no <doc>'s. numFound does not equal total for both cores
(131+302=433).
