best way to get number of documents in a Solr index

Hello,

I am looking for the best way to get the number of documents in a Solr 
index. I'd like to do it from a java code using solrj. Any suggestions 
are welcome.

Thank you in advance,
Maria mosolova

try a query with q=*:*

the 'numFound' will be every document -- use &rows=0 to avoid returing 
docs (if you like)

   public int resultCount() {
     try {
       SolrQuery q = new SolrQuery("*:*");
       QueryResponse rq = solr.query(q);
       return rq.getResults().getNumFound();
     } catch (org.apache.solr.client.solrj.SolrServerException e) {
       System.err.println("Query problem");
     } catch (java.io.IOException e)  {
       System.err.println("Other error");
     }
     return -1;
   }
