Test Harness for DNN ISearchable

Testing an implementation of the DNN ISearchable interface implementation for a module can be time-consuming and slow if you rely on the DNN search engine indexer to run and then either check the database for results or use the Search UI. There is a simpler way.

Copy and paste the below script into DNNSearch.aspx (or grab the attachment at the end of this post), place the file in the root folder of your app and you can test ISearchable for any module instance with ease. The script requires you to provide a TabId and a ModuleId. It then queries the database for the BusinessController defined in the DesktopModules table and instantiates it exactly as the DNN search indexer does. It then calls GetSearchItems() and displays the results.

Unlike the DNN search indexer, DNNSearch does not make any changes to the database. It is useful only for testing if the ISearchable implementation is working correctly and does not provide any insights into any issues that the search index provider you are using may have.
