SolrDocumentList Size vs NumFound

Dear all,

I got a weird problem. The number of searched documents is much more than
10. However, the size of SolrDocumentList is 10 and the getNumFound() is the
exact count of results. When I need to iterate the results as follows, only
10 are displayed. How to get the rest ones?

                ......
                for (SolrDocument doc : docs)
                {

System.out.println(doc.getFieldValue(Fields.CATEGORIZED_HUB_TITLE_FIELD) +
": " + doc.getFieldValue(Fields.CATEGORIZED_HUB_URL_FIELD) + "; " +
doc.getFieldValue(Fields.HUB_CATEGORY_NAME_FIELD) + "/" +
doc.getFieldValue(Fields.HUB_PARENT_CATEGORY_NAME_FIELD));
                }
                ......

Could you give me a hand?

Thanks,
LB

Hi,

If your query yields 1000 documents and the rows parameter is 10 then you'll 
get only 10 documents.  Consult the wiki on the start and rows parameters:

Cheers.
