Hello Renee,
By default you cannot set which items to be indexed. The NewsIndex gets all published IContent items from a given provider and the crawler gets all data. Then in our provider we build the news url. You can tweak the built-in news provider and implement filtering based on category or any other specific parameters you would like to use.
here is a sample code that will add only items from a certain category to the index
public class NewsIndexProviderCustom : Telerik.News.NewsIndexProvider
{
public NewsIndexProviderCustom()
{
//
// TODO: Add constructor logic here
//
}
public override Telerik.Framework.Search.IIndexerInfo[] GetContentToIndex()
{
//return base.GetContentToIndex();
if (this.retrievalMethod != RetrievalMethod.Direct)
return new IIndexerInfo[0];
if (this.manager == null)
throw new InvalidOperationException("Manager is null");
IMetaSearchInfo[] filter = this.manager.GetFilter(this.FilterExpression);
if (ContentManager.Providers[DataProviderName].MetaKeys.ContainsKey("Category"))
{
List<IMetaSearchInfo> newFilter = new List<IMetaSearchInfo>(filter);
MetaSearchInfo searchInfo = new MetaSearchInfo(MetaValueTypes.DateTime, "Publication_Date", "SomeName", SearchCondition.Equal);
newFilter.Add(searchInfo);
filter = newFilter.ToArray();
}
IList itemsList = this.manager.GetContent(0, 0, String.Empty, ContentStatus.Published, this.ParentIDs, filter);
List<IContent> lst = new List<IContent>();
foreach (IContent cnt in itemsList)
{
if (!lst.Contains(cnt))
lst.Add(cnt);
}
List<IIndexerInfo> data = new List<IIndexerInfo>(lst.Count);
foreach (IContent content in lst)
{
if (content != null)
{
if (this.manager.Provider.AllowLocalization)
{
foreach (string lng in content.Languages)
{
CultureInfo cult = CultureInfo.GetCultureInfo(lng);
string path = this.GetItemUrl(content, this.baseUrl, cult);
data.Add(this.GetIndexerInfo(path, content, cult));
}
}
else
{
string path = this.GetItemUrl(content, this.baseUrl, null);
data.Add(this.GetIndexerInfo(path, content));
}
}
}
return data.ToArray();
}
}
You can register the provider in your web.config
All the best,
