Hi Chriztian

Changing from search to indexer returns the following error:

System.NotSupportedException: XSLT Extensions are only support for providers of type LuceneSearcher 
at UmbracoExamine.XsltExtensions.EnsureProvider(BaseSearchProvider p) 
at UmbracoExamine.XsltExtensions.Search(String searchText, Boolean useWildcards, String providerName, String indexType)
