I want to join this thread because I have just had this problem big time! The
ON search utility stopped working altogether - other than finding a string on
the actual page I was on. [Yes - I had set it to Search All Notebooks]. The
odd thing was that, when I did the Desktop search on the same string it found
all 6 occurrences of it throughout OneNote! So the problem clearly lay
within OneNote, although I did also rebuild my Windows index using the
Indexing options module in Control Panel, Advanced, Rebuild. Probably not
necessary but I did it anyway.
None of this worked, so I put the OneNote CD in and hit 'Repair'. That
didn't work either.
I then put all my Notebooks on a memory stick, deleted them from my hard
drive, completely uninstalled OneNote, removed three PowerToys, re-installed
OneNote, and put my Notebooks back on to the hard drive.
It worked!! I had been staring the spectre of a full System Restore in the
face so I was relieved. But the question remains - why did this happen? How
can the Search utility in OneNote suddenly decide not to work?
Could the PowerToys I had downloaded - Page Merge, Sort Pages and Favorites
- have caused the problem? I want to put two of those back but will wait for
feedback to this before I do!
It interests me that the search facility worked instantly after the
re-install. It didn't have any time to index anything - but it still worked.
Clever.
