Hi,
I have a four indexes which I'm sharding together for our general search
system, each Index has
it's own solr search webapp in tomcat and they all produce correct results
individually.
Two of the indexes when sharded together return the correct numFound and a
loaded
SolrDocumentList, when I add one of the other two indexes the numFound
will change to the
correct value but the SolrDocumentList will be empty.
I have tried a number of shard configurations and whilst the problem core
is in the shard list the
SolrDocumentList will always be empty, even with just the problem index as
the only one in the
shard list it still returns a count in the numFound field with an empty
SolrDocumentList .
I've tried changing the schema.xml on each index to only three fields and
removed any unused
types (see schema.xml below) id,search field and facet field but this made
no difference. I've also
shrunk one of the problem indexes down to a single document but the
problem still occurs.
One of the indexes that works is generated using the solr
DataImportHandler whilst another one
of the working indexes is generated in Lucene.
I've searched for this issue in solr-user and found two other people with
the same problem but no resolution.
Multiple shards on same machine find matches but return 0 results. (by

Many thanks for your time.
