Start Lucene search index update from code

Is it possible to start an update or a partial update of the Lucene index from custom code?

I'm importing a lot of filters and products via some activites, and i'd like to update the index once all these imports are done.

Regards
Martin

Hi, try please this code:

Imports Dynamicweb.Extensibility.Searching

' *** Dynamicweb Searching ***

' Running all pending index updates

If Not ScheduledUpdate.StartupTaskIsExecuted Then

If Not HttpRuntime.UsingIntegratedPipeline Then

For Each u As ScheduledUpdate In ScheduledUpdate.GetPendingUpdates(ScheduledUpdateType.StartupTask)

' Update will be performed asynchronously

Dynamicweb.Searching.Management.IndexUpdateService.Current.CreateTask(u.Path, u.IsFullUpdate)

' Updating "Last executed" timestamp

u.LastExecuted = DateTime.Now

u.Save()

End If

ScheduledUpdate.StartupTaskIsExecuted = True

End If

Kind Regards

Hi Martin and Yury,

Yury, this approach won't work because the code relies on a "Scheduled updates" settings (Management Center -> eCommerce -> Advanced configuration -> Searching -> Right click on "Products" -> "Scheduled updates") so if you didn't configure that then the update won't execute.

There is a much simpler (and recommended) approach:

1. Non-blocking (asynchronous) update:

var isFullUpdate = false;
Dynamicweb.Searching.Management.IndexUpdateService.Current.CreateTask("Products", isFullUpdate);

2. Blocking (synchronous) update:

var isFullUpdate = false;
Dynamicweb.Searching.IndexManager.Current.UpdateIndex("Products", isFullUpdate);

Please note that you need to add a reference to "Dynamicweb.Searching" in your project before you can use this APIs.

Hi Everybody.

FYI - If your DW solution is Integrated with Navision and you want to update the index after import. Create a PipeLine with Pavel's solution 2. (Synchronous) and place it as the last pipeline in the import. Otherwise the index will, in some cases, fail with an object reference not set to an instance of an object. Don't know why, but it works with

Dynamicweb.Searching.IndexManager.Current.UpdateIndex("Products", isFullUpdate);

and not with

Dynamicweb.Searching.Management.IndexUpdateService.Current.CreateTask("Products", isFullUpdate);

I can just add that

Dynamicweb.Searching.IndexManager.Current.UpdateIndex("Products", isFullUpdate);

is in use in our Product Import Activity from next release (so we've done the same changes as you, based on your case). ;-)
