WorkSite SDK 'SearchWorkspaces' function problem

DVM

I can't seem to get the WorkSite SDK 'SearchWorkspaces ()' function working against a FileSite (v8.00.52) database. I'm new to both the SDK & WorkSite/FileSite.

Is there a 'FileSite SDK' that I should be using, instead of the 'WorkSite SDK'? I'm writing my app in C#.

It doesn't matter what type of 'workspace' search parameter I specify, I can't seem to retrieve any results. The only successful search, is the one where I specify an empty search parameter 'value':

IManProfileSearchParameters profSearchParams =
imanDms.CreateProfileSearchParameters ();
if (profSearchParams == null)
{
Debug.Assert (false);

return -1;
}
IManWorkspaceSearchParameters wkspcSearchParams =
imanDms.CreateWorkspaceSearchParameters ();
if (wkspcSearchParams == null)
{
Debug.Assert (false);

return -1;
}

// NOTE: It works!!!
wkspcSearchParams.Add
(
imFolderAttributeID.imFolderDescription,
@""
);

IManFolders flds =
imanLFDb.SearchWorkspaces
(profSearchParams, wkspcSearchParams);

What's the deal? Have I done something wrong?? Is the search completely broken???

I have tried the search database option from the UI but that doesn't seem to give me any results either?!!?!??

Please can someone shed some light upon the matter.

Thanks (in advance).
