Yes, Exporting Results Sets is the preferred and recommended technique for returning all documents in a collection, or even simply for queries that select a large number of documents, all of which are to be returned. It uses efficient streaming rather than paging.
But... this great feature currently does not have support for distributed/SolrCloud mode: "The initial release treats all queries as non-distributed requests. So the client is responsible for making the calls to each Solr instance and merging the results. Using SolrJ’s CloudSolrClient as a model, developers could build clients that automatically send requests to all the shards in a collection (or multiple collections) and then merge the sorted sets any way they wish." -- Jack Krupansky On Wed, Jan 20, 2016 at 8:41 AM, Susheel Kumar <susheel2...@gmail.com> wrote: > Hello Salman, > > Please checkout the export functionality > https://cwiki.apache.org/confluence/display/solr/Exporting+Result+Sets > > Thanks, > Susheel > > On Wed, Jan 20, 2016 at 6:57 AM, Emir Arnautovic < > emir.arnauto...@sematext.com> wrote: > > > Hi Salman, > > You should use cursors in order to avoid "deep paging issues".
