Hello! You can upload new schema.xml (along with other configuration files) and reload the collection using collections API (http://wiki.apache.org/solr/SolrCloud#Managing_collections_via_the_Collections_API). However you have remember that in order for the new field to be usable documents needs to be re-indexed.
You can't just add new shard (you can add replicas though), but you can re-shard your current collection. Look at the collections API and the SPLITSHARD command, don't know which Solr you are using, but the SPLITSHARD is supported since Solr 4.3. -- Regards, Rafał Kuć Sematext :: http://sematext.com/ :: Solr - Lucene - ElasticSearch > Hi, > I have couple of usecase need to be implemented. > 1.
