Member	Peter - 5/30/2013 12:01:36 AM Update smart index after edit, delete, insert document via API Hi, Is there a way to update existing index in code after I've inserted, deleted or updated a document through the code? I understand there is a rebuild on every index but was wondering if there is a method to call which would just update the index. Thanks for any help Peter

This should get you what you need.

/// <summary>
/// Rebuilds an index based on the index name
/// </summary>
/// <param name="indexName"></param>
/// <returns></returns>
private bool RebuildIndex(string indexName)
{
    // Get the search index
    SearchIndexInfo index = SearchIndexInfoProvider.GetSearchIndexInfo(indexName);
    if (index != null)
    {
        // Create rebuild task 
        SearchTaskInfoProvider.CreateTask(SearchTaskTypeEnum.Rebuild, index.IndexType, null, index.IndexName);
        return true;
    }
    return false;
}


Member	Peter - 5/30/2013 4:59:21 PM RE:Update smart index after edit, delete, insert document via API Thanks for that I actually got the following and it works. Unfortunatelly it is not imidiate update of the index I would like. SearchTaskInfoProvider.CreateTask(SearchTaskTypeEnum.Update, PredefinedObjectType.DOCUMENT, SearchHelper.ID_FIELD, node.GetSearchID()); Regards

RE:Update smart index after edit, delete, insert document via API

Hello Peter,

You can execute the same code, which is executed when you rebuild smart search index manually in Site Manager -> Administration -> Smart search -> edit -> General tab -> Rebuild link button. This code can be found in <project folder>\CMSModules\SmartSearch\Controls\UI\SearchIndex_General.ascx.cs.

At first, you need to create SmartSearchInfo object:

protected SearchIndexInfo sii = null; //(around line 26)

And assign proper index to it:

// Get search index info //(around line 65)
sii = SearchIndexInfoProvider.GetSearchIndexInfo(this.ItemID);
{
// see code inside
}

If you know ID of selected index, you can use it directly.

Then you can rebuild index using this code:

if (sii != null)
{
SearchTaskInfoProvider.CreateTask(SearchTaskTypeEnum.Rebuild, sii.IndexType, null, sii.IndexName);
}

lblInfo.Text = ResHelper.GetString("srch.index.rebuildstarted");
lblInfo.Visible = true;

// Reload info panel
System.Threading.Thread.Sleep(100);
ReloadInfoPanel();
}

Please take an inspiration from file above for more details.

Best regards,
Martin Danko

RE:Update smart index after edit, delete, insert document via API

Thanks Martin,

I was using the rebuild method, however I don't want to rebuild the whole index if I update 1 item. The following code is what I ended up with.

    private void UpdateSearchIndex(CMS.DocumentEngine.TreeNode node, SearchTaskTypeEnum type)
    {
        SearchIndexInfo index = SearchIndexInfoProvider.GetSearchIndexInfo("EWGSiteExperts");
        Lucene.Net.Documents.Document iDoc = node.GetSearchDocument(index as ISearchIndexInfo);

        if (type == SearchTaskTypeEnum.Update)
        {
            SearchHelper.Update(iDoc, index);
        }
        else if (type == SearchTaskTypeEnum.Delete)
        {
            SearchTaskInfo sti = new SearchTaskInfo();
            sti.SearchTaskType = type;
            sti.SearchTaskField = SearchHelper.ID_FIELD;
            SearchHelper.Delete(sti.SearchTaskField, node.GetSearchID(), index);
        }
    }
