Hello there Mark!
With SolrJ, you can simply do the following:
server.query(q) returns QueryResponse
the queryResponse has the method getResults() which returns
SolrDocumentList. This is an extended list containing SolrDocuments, but
it also exposes methods such as getNumFound(), which is exactly what you
are looking for!
so, you could do something like this:
int hits = solrServer.query(q).getResults().getNumFound();
and you have similar methods for the other attributes, like:
results.getMaxScore();
and
results.getStart();
Hope that helps.
Cheers, and merry Christmas!

Hello,
I am trying to get the numFound attribute from a returned QueryResponse
object, but for the life of me I can't find where it is stored. When I
view
a response in XML format, it is stored as an attribute on the response
node,
e.g.:
<result name="response" numFound="207" start="5" maxScore="4.1191907">
However, I can't find a way to retrieve these attributes (numFound, start
and maxScore). When I look at the QueryResponse itself, I can see that
the
attributes are being stored somewhere, because the toString method
returns
them. For example, queryResponse.toString() returns:
{responseHeader={status=0,QTime=139,params={wt=javabin,hl=true,rows=15,version=2.2,fl=urlmd5,start=0,q=java}},response={
*numFound=1228*,start=03.633028,docs=[SolrDocument[{urlmd5=...
The problem is that when I call queryResponse.get('response'), all I get
is
the list of SolrDocuments, I don't have any other attributes. Am I
missing
something or are these attributes just not publically available? If
they're
not, shouldn't they be? Thanks a lot,
Mark Ferguson
