search provider error on virto commerce

I setup Virto Commerce from source code following the guide here http://docs.virtocommerce.com/display/vc1devguide/Source+code+getting+started

I set Lucene as search provider in connectionString.local.config file

<add name="VirtoCommerce" connectionString="Data Source=localhost\sqlexpress;Initial Catalog=VirtoCommerce;Integrated Security = true;MultipleActiveResultSets=True;Connect Timeout=420"
    providerName="System.Data.SqlClient" />

<add name="SearchConnectionString" connectionString="server=~/app_data/virto/search;scope=default;provider=lucene" />

I don't see any index files generated here "App_Data\Virto\Search\default-catalogitem". When I try to open the site on browser I am getting following error

no segments* file found in Lucene.Net.Store.SimpleFSDirectory@C:\work\virtocommerce\src\Presentation\FrontEnd\StoreWebApp\app_data\Virto\search/default-catalogitem lockFactory=Lucene.Net.Store.NativeFSLockFactory: files:

Source File: c:\work\virtocommerce\src\Extensions\Search\LuceneSearchProvider\LuceneSearchProvider.cs    Line: 253

I have run the setup-search powershell script but it doesn't help.

Thanks

Solution

Try rebuilding the search index in Commerce Manager http://docs.virtocommerce.com/display/vc1userguide/Search+Settings
