With Find-backed IEntrySearchService in the previous post , we can now put SearchProvider to rest. There are, however, parts of the framework that still rely on SearchManager, and it expects a configured, working SearchProvider. The Full search index job, and the Incremental search index job are two examples. To make sure we don’t break the system, we might want to give SearchManager something to chew on. A do nothing SearchProvider that is!

And we need a DoNothingSearchProvider

    public class DoNothingSearchProvider : SearchProvider
    {
        public override string QueryBuilderType => GetType().ToString();

        public override void Close(string applicationName, string scope) { }
        public override void Commit(string applicationName) { }
        public override void Index(string applicationName, string scope, ISearchDocument document) { }
        public override int Remove(string applicationName, string scope, string key, string value)
        { return 42; }

        public override void RemoveAll(string applicationName, string scope)
        {
        }
        public override ISearchResults Search(string applicationName, ISearchCriteria criteria)
        {
            return new SearchResults(new SearchDocuments(), new CatalogEntrySearchCriteria());
        }
    }

    

And a DoNothingIndexBuilder

public class DoNothingIndexBuiler : ISearchIndexBuilder
    {
        public SearchManager Manager { get; set; }
        public IndexBuilder Indexer { get; set; }

        public event SearchIndexHandler SearchIndexMessage;

        public void BuildIndex(bool rebuild) { }
        public bool UpdateIndex(IEnumerable<int> itemIds) { return true; }
    }

What remains is simply register them in your appsettings.json

                                       "SearchOptions":  {
                                                             "DefaultSearchProvider":  "DoNothingSearchProvider",
                                                             "MaxHitsForSearchResults":  1000,
                                                             "IndexerBasePath":  "[appDataPath]/Quicksilver/SearchIndex",
                                                             "IndexerConnectionString":  "",
                                                             "SearchProviders":  [
                                                              {
                                                                "Name": "DoNothingSearchProvider",
                                                                "Type": "EPiServer.Reference.Commerce.Site.Infrastructure.Indexing.DoNothingSearchProvider, EPiServer.Reference.Commerce.Site",
                                                                "Parameters": {
                                                                  "queryBuilderType": "EPiServer.Reference.Commerce.Site.Infrastructure.Indexing.DoNothingSearchProvider, EPiServer.Reference.Commerce.Site",
                                                                  "storage": "[appDataPath]/Quicksilver/SearchIndex",
                                                                  "simulateFaceting": "true"
                                                                }
                                                              }
                                                                                 ],
                                                             "Indexers":  [
                                                                              {
                                                                                  "Name":  "catalog",
                                                                                  "Type":  "EPiServer.Reference.Commerce.Site.Infrastructure.Indexing.DoNothingIndexBuilder, EPiServer.Reference.Commerce.Site"
                                                                              }
                                                                          ]
                                                         },

And that’s it.
