Hello,
I played around some more with it and I found out that I was pointing my
constructor to an older class that doesn't have the MultiCore capability.
This is what I did to set up the shards:
query.setParam("shards",
"localhost:8080/solr/core0/,localhost:8080/solr/core1/");
I do have a new issue with this though. Here is how the results are
displayed:
QueryResponse qr = server.query(query);
SolrDocumentList sdl = qr.getResults();
System.out.println("Found: " + sdl.getNumFound());
System.out.println("Start: " + sdl.getStart());
System.out.println("Max Score: " + sdl.getMaxScore());
System.out.println("--------------------------------");
ArrayList<HashMap<String, Object>> hitsOnPage = new
ArrayList<HashMap<String, Object>>();
for(SolrDocument d : sdl)
{
HashMap<String, Object> values = new HashMap<String,
Object>();
for(Iterator<Map.Entry<String, Object>> i = d.iterator();
i.hasNext(); )
{
Map.Entry<String, Object> e2 = i.next();
values.put(e2.getKey(), e2.getValue());
}
hitsOnPage.add(values);
String outputString = new String( values.get("title") );
System.out.println(outputString);
}
The field "title" is one of the common fields that is shared between the two
schemas. When I print the results of my query, I get null for everything.
However, the result of sdl.getNumFound() is correct, so I know that both
cores are being accessed.
Is there a difference with how SolrJ handles multicore requests?
