Catastrophic failure when searching subsites

Microsoft.SharePoint.SPException: Catastrophic failure --->
System.Runtime.InteropServices.COMException

I am trying to write a web part that will return search results across all
subsites within a site and have run into a strange error. I found questions
about this error already posted in several newsgroups - but no solution :-(

1)
I first get the current (root) web using the following line:
SPWeb oRoot =SPControl.GetContextWeb(this.Context).Site.RootWeb;

2)
I can then search the documents and lists by using the following lines:
SPSearchResultCollection oRootDocResults =
oRoot.SearchDocuments(SearchString);
--> this works ok!

3)
I now need to get all of the subsites that the current user has permissions
to view and then I loop through all of these sites and call the
SearchDocuments method. This is where the problem occurs.
SPWebCollection subSites = oRoot.GetSubwebsForCurrentUser();
SPSearchResultCollection oDocResults;
for (int i=0;i<subSites.Count;i++)
{
oDocResults = subSites[i].SearchDocuments(SearchString);
}

When the SearchDocuments method is called I get the following error:

Microsoft.SharePoint.SPException: Catastrophic failure --->
System.Runtime.InteropServices.COMException

I am at a loss as to why this is occuring. Any ideas or suggestions?
I am really in a bind and need to get cross-site search running.
Thanks in advance!

Re: Catastrophic failure when searching subsites

Hi Martin,

I'm just guessing here, but what if you tried this:

SPWebCollection subSites = oRoot.GetSubwebsForCurrentUser();
SPSearchResultCollection oDocResults;

foreach (SPWeb searchWeb in subSites)
{
oDocResults = searchWeb.SearchDocuments(SearchString);
}

Does that help?

Are you getting the error the first time trhough the loop, or the second?
Keep in mind that the oDocResults is redefined each time through the loop;
i.e. the results of the search are not added to the SPSearchResultCollection
but replace them.

Re: Catastrophic failure when searching subsites

Hi Jim,

Thank you but no, that doesn't help.
The code I posted was from a first quick and dirty trial.
What I really want to do is in VB and looks like this:

Private Sub searchWeb(ByVal web As SPWeb, ByRef output As
System.Web.UI.HtmlTextWriter)
Dim subWeb As SPWeb
Dim src As SPSearchResultCollection = web.SearchDocuments(SearchString)
For Each sr As SPSearchResult In src
'Render out the search results...
Next
Dim subWebs As SPWebCollection = web.GetSubwebsForCurrentUser()
For Each subWeb In subWebs
searchWeb(subWeb, output)
Next
End Sub

This works fine for the root web. But in the recursive iterations, the
web.SearchDocuments(SearchString) throws the Catastrophic Failure
exception...

Any other ideas would be greatly appretiated!

Martin
