In my SolrCloud, I have set up a collection with multiple cores. The following /export request handler query is not including the results from all the cores.
http://localhost:8983/solr/my_collection_name/export?indent=true&q.op=OR&q=*:*&fq=((Ar:(*srikanth*))%20OR%20(F_Name:(*srikanth*))%20OR%20(Mobile:(*srikanth*))%20OR%20(Name:(*srikanth*))%20OR%20(O_m_no:(*srikanth*))%20OR%20(Addr:(*srikanth*)))&wt=json&sort=id+desc&fl=Name,Mobile,F_Name
Following /select request handler is showing the results from all the cores.
