Hi,
unfortunately you cannot search for Vault status (file local or not), as it is determined in the context of the folder whether a local copy exists or not.
I don't know for sure what you are trying to achieve with this search in the end, but my guess is that you want to keep your workspace up to date and organised. Productstream 2009 brings you workspace synchronization: The new Workspace Synchronization command reduces the need to manually manage the local workspace. the command supports two primary operations: downloading and updating out-of-date files and removing files that fall within the expiration rules. Outdated files are moved the Windows Recycle bin.
Please let me know if this is what you were looking for.
