No documents found when using IWOVServices.SearchDocuments web service

wwest

I am attempting to use the IWOVServices.SearchDocuments web service to retrieve a list of matching documents for a simple piece of text that does exist in the description of many documents in the library I am searching. The cacc runs successfully, but the document count is always zero - I have included the main portion of code that calls the service below. The same search from the wwworksiteweb front-end works correctly - it returns many documents. Am I missing something?

Thanks,

do you get anything if you comment out...

'search email and/or documents?
Dim searchEmail As New IWOVServices.imSearchEmail
searchEmail = IWOVServices.imSearchEmail.imSearchDocumentsOnly
testSearchInput.SearchEmail = searchEmail
