Though I have indexing set to index filenames and contents of .one files,
Vista search never finds anything in OneNote except filenames.  For example,
a file might exist called travel.one with the word "Paris" in the file.  A
search for "travel" finds travel.one, but a search for "Paris" does not
locate its appearance within that file.  I do have "search entire index"
selected in the Start menu customization.  Can the contents of OneNote be
indexed and searched?
