Example

Sub UserProc;
Var
    MB: IMetabase;
    SharedParams: ISharedParams;
    SearchEngine: ISolrSearchEngineService;
    Core: ISolrSearchEngineCore;
    Operations: ISolrOperations;
    Arr: Array;
Begin
    MB := MetabaseClass.Active;
    SharedParams := MB.SpecialObject(MetabaseSpecialObject.SharedParams).Bind As ISharedParams;
    SearchEngine := SharedParams.SearchEngine As ISolrSearchEngineService;
    Core := SearchEngine.Cores.Item(0);
    Arr := New Variant[1];
    Arr[0] := "Cube";
    Operations := New SolrOperations.Create;
    Operations.RemoveDocsByFieldName(Core, "name", Arr);
End Sub UserProc;

On executing the example the Solr documents, which are linked with the name field and which contain the Cube indexed value, will be removed.
