Guido commented on SOLR-6167: ----------------------------- You was right: I solved this issue by modifying my library accordingly to the new version of Solr. Thank you very much for your help. Best Regards, Guido > SolrDocumentList cannot be cast to ResultContext on Solr 4.8.0 > -------------------------------------------------------------- > > Key: SOLR-6167 > URL: https://issues.apache.org/jira/browse/SOLR-6167 > Project: Solr > Issue Type: Bug > Components: clients - php > Affects Versions: 4.8 > Environment: Linux > Reporter: Guido > Labels: ResultContext, SolrSolrDocumentList, solrcloud > > Hello, > I have a running instance of Solr 4.2.1 (I will refer to it as 'instance A') > and I am trying to pass to Solr 4.8.0. For this purpose, I created a copy of > the machine which hosts 'instance A' (I will refer to the copy as 'instance > B') and, on this new machine, I have installed Solr 4.8.0 and I have created > a collection with 4 shards. Then, on the new machine, I have iterated over a > copy of the index built on instance A and I have re-indexed all the documents > and inserted them inside the new collection of Solr 4.8.0. I have completed > this process, the two index seem to contain the same documents and I am > successfully able to query properly both the indexes. > When I try to run the following query on 'instance A': > http://instance_A_ip:23332/solr/myindex/query?q=id%3Amyid&fl=html&wt=html > I get a well formatted html response.
