Hi, I have Implemented two project in same solution, that is one for Mvc Project and Another for Mvc Umbraco. but here i have implemented Dynamic Search Feature ,if i search its going to search in both mvc and Umbraco and Displaying the result. I have customeDataservice.cs file too.In this file i'm getting mvc search values. public class CustomDataService :ISimpleDataService { public CustomDataService() { }

    public IEnumerable<SimpleDataSet> GetAllData(string indexType)
    {
        var data = new List<SimpleDataSet>();
        SeabEntityContext seabEntityContext = new SeabEntityContext();
        CategoryRepository categoryRepository = new CategoryRepository(seabEntityContext);
        LanguageRepository languageRepository = new LanguageRepository(seabEntityContext);
        BrandRepository brandRepository = new BrandRepository(seabEntityContext);
        ProductRepository productRepository = new ProductRepository(seabEntityContext);
        ProductViewModelRepository ProductViewModel = new ProductViewModelRepository(productRepository, languageRepository, brandRepository, categoryRepository);
        List<ProductViewModel> things = ProductViewModel.GetAllProducts();

        foreach (ProductViewModel thing in things)
        {
            data.Add(new SimpleDataSet()
            {
                NodeDefinition = new IndexedNode()
                {
                    NodeId = thing.Id,
                    Type = "content"
                },
                RowData = new Dictionary<string, string>()
            {
                {"title", thing.ProductName},
                {"contents", thing.ProductLanguages.FirstOrDefault().ProductSubTitle}
            }
            });
        }

        return data;
    }

In Examinesetting.config file i have added customeindexer.

  <add name="InternalMemberIndexer" type="UmbracoExamine.UmbracoMemberIndexer, UmbracoExamine"
       supportUnpublished="true"
       supportProtected="true"
       analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net" />


  <!-- default external indexer, which excludes protected and published pages-->
  <add name="ExternalIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"
           supportUnpublished="false"
           supportProtected="false"
           analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net" />
  <add name="ExternalMemberIndexer" type="UmbracoExamine.UmbracoMemberIndexer, UmbracoExamine"
       supportUnpublished="true"
       supportProtected="true"
       analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net" />


  <add name="CustomIndexer" type="Examine.LuceneEngine.Providers.SimpleDataIndexer, Examine"
             dataService="Seab.Umbraco.Service.CustomDataService, Seab.Umbraco.Service" indexSet="CustomIndexSet" runAsync="true" />

  <add name="CustomMemberIndexer" type="UmbracoExamine.UmbracoMemberIndexer, UmbracoExamine"
       supportUnpublished="true"
       supportProtected="true"
       analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net" />
</providers>

  <add name="ExternalSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"

analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net" enableLeadingWildcards="true" />

  <add name="InternalMemberSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"
       analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net" enableLeadingWildcard="true" />

  <add name="ExternalMemberSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"
       analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net" enableLeadingWildcard="true" />

  <add name="CustomSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"

analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net" enableLeadingWildcard="true" dataService="Seab.Umbraco.Service.CustomDataService, Seab.Umbraco" indexSet="CustomIndexSet" />

  <add name="CustomMemberSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"
       analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net" enableLeadingWildcard="true" dataService="Seab.Umbraco.Service.CustomDataService, Seab.Umbraco" indexSet="CustomIndexSet" />
</providers>

And i have changed Examineindex.config file too. when i trying to search it Throws an Error "Value cannot be null.Parameter name: The indexTypes property must be specified for the SimpleDataIndexer provider"
