I'm working on a project that is using Umbraco containing two websites. I want to make a search for one of the sites that is not indexing the other website. I've created the extension showed below.

1. On the GatherNodeData event my extension comes in
2. I check if I'm dealing with Content and if the path attibute is present
3. With my custom Helper I only check if the NodeTypeAlias name mathes "CorporateHome" in the path
4. If it isn't I cancel the event

Here comes the big question:

When I cancel the GatherNodeData event is this only for the current node or the whole proces of indexing?

    public class CancelIndexerOnNonCorporateContent : ApplicationBase
    {
        /// <summary>
        /// Initializes a new instance of the <see cref="CancelIndexerOnWoningWebsite"/> class.
        /// </summary>
        public CancelIndexerOnNonCorporateContent()
        {
            ExamineManager.Instance.IndexProviderCollection["CorporateContentIndexer"].GatheringNodeData +=
                CancelIndexerOnNonCorporateContent_GatheringNodeData;
        }

        /// <summary>
        /// Handles the GatheringNodeData event of the CancelIndexerOnNonCorporateContent control.
        /// </summary>
        /// <param name="sender">The source of the event.</param>
        /// <param name="e">The <see cref="Examine.IndexingNodeDataEventArgs"/> instance containing the event data.</param>
        private void CancelIndexerOnNonCorporateContent_GatheringNodeData(object sender, IndexingNodeDataEventArgs e)
        {
            if (e.IndexType == "Content" && e.Node.Attribute("path") != null)
            {
                string[] pathIds = e.Node.Attribute("path").Value.Split(',');
                bool isInCorporatePath =
                    pathIds.Where(i => UmbracoHelper.GetNodeTypeAlias(Convert.ToInt32(i)) == "CorporateHome").Any();

                if (!isInCorporatePath)
                {
                    e.Cancel = true;
                }
            }
        }
    }
