Solr.Net Cluster Query

[Angelo Strano]

Hi Mauricio,

I'm trying to look for clustering solr.net but can not understand which object to use.

Solr is working properly and provides the cluster results correctly.

I am using the following code:

ISolrOperations<T> solr = ServiceLocator.Current.GetInstance<ISolrOperations<T>>();

QueryOptions QueryOptions = new QueryOptions();

lusteringParameters cluParam = new ClusteringParameters();

cluParam.Algorithm = "org.carrot2.clustering.lingo.LingoClusteringAlgorithm";

cluParam.Engine = "Lingo";

cluParam.ProduceSummary = true;

cluParam.Snippet = "document_content_text";

cluParam.Results = true;

cluParam.Title = "name";

cluParam.Url = "id";

cluParam.LexicalResources = "clustering/carrot2";

cluParam.SubClusters = false;

cluParam.NumDescriptions = 5;

QueryOptions.Clustering = cluParam;

"omissis"

ClusterResults results = solr.Query(new SolrMultipleCriteriaQuery(Queries.ToArray(), Operator.ToString()), QueryOptions).Clusters;

 

Clusters property is always null.

Could you help me

Thank you

Can you check if the response format has changed from what we have in the current tests?
