Is there any desktop search application (e.g. WDS, Copernic, Google
Desktop) that will search Onenote notebooks from outside of Onenote
and present a PREVIEW of the results?

I have WDS 3.0 installed on one machine and it points to onenote
pages with the text that I am searching for but it doesn't present any
preview (it just links to a stub indicating the file-folder
location).

If not available now, does anybody know of any plans for WDS to
support preview via external searches in the future? Any other
solutions? Thanks.
