Core admin

SolrNet offers some facilities to execute Solr core admin commands. See the Solr wiki for detailed explanations of these commands.

First, build an instance of ISolrCoreAdmin:

const string solrUrl = "http://localhost:8983/solr";
var headerParser = ServiceLocator.Current.GetInstance<ISolrHeaderResponseParser>();
var statusParser = ServiceLocator.Current.GetInstance<ISolrStatusResponseParser>();
ISolrCoreAdmin solrCoreAdmin = new SolrCoreAdmin(new SolrConnection(solrUrl), headerParser, statusParser);

ISolrCoreAdmin can execute the following core admin commands:

Status

/// Get the status of all registered cores:
IList<CoreResult> coreStatus = solrCoreAdmin.Status();

/// Get the status of a single core:
var coreStatus = solrCoreAdmin.Status("core1");

Create

solrCoreAdmin.Create(coreName: "items", instanceDir: "items");

Reload

solrCoreAdmin.Reload("core1");

Rename

solrCoreAdmin.Rename("core1", "newCoreName");

Swap

solrCoreAdmin.Swap("core0", "core1");

Unload

solrCoreAdmin.Unload("core0", UnloadCommand.Delete.Data);

Merge

solrCoreAdmin.Merge("destinationCore", new MergeCommand.SrcCore("sourceCore0"), new MergeCommand.SrcCore("sourceCore1"));

Alias

solrCoreAdmin.Alias("existingCore", "alias");
