SearchResult.aspx.cs could not return any results. Is there anything needed in the configuration file.
The configuration for episerver.search and the configuration for episerver.search.indexingservice should be compatible.
(ie, the configuration for episerver.search should reference the appropriate url for where the indexing service is set up and the indexing service should allow the appropriate client)
Also, the index should allow updating (readOnly="false") for the client site where content is created.
