On my EPiServer 6.0 site, I have set up a search page which is an exact copy of the Search.aspx page from the default EPiServer installation. But when I try to search my site using it, it never returns any results. Searching for file by name or content works correctly in the File Management Admin interface, so it looks like search is working to some extent.
Could you post the code for search.aspx please.
And I suppose you have properties in the pages marked as searchable in the page type definition?
