I have over 40000 documents in various library for a site collection. When setting up scope for this (IsDocument=1) i only see 74 in the item count. Full crawl is set to run every night. Where should I look to fix this?
The Item Count on the Search Scopes is only an estimate and can be wildly out.
When you perform a search in your search center on the scope for all documents do you get the full ~40,000 items or just 74?
To do a search for all documents use a part of the URL. For example if your site URL is http://www.contoso.com/sites/Mysite then do a search for "Contoso" to match all documents.
