Windows 7 search keeps rebuilding index even though indexing was complete

Windows 7 keeps rebuilding index even though indexing was complete with about 203,000 items. Search was fast and accurate but then the next time the laptop was rebooted, index was rebuilding from scratch again. What triggered off the rebuilding of index automatically?

I am happy to report that my re-indexing problem has inexplicably resolved itself. It is a mystery; I am not sure what happened as I believe I have done the following previously to no avail.


1.      Checked and repaired .pst file with scanpst.exe

2.      Reboot laptop

3.      Launched Outlook 2010 , go to File tab

Select Options

Select Search

Click Indexing Options

Click Advanced

Click Rebuild

4.      After 10 hours or so, indexing was complete


Miraculously, no re-indexing has taken place in the past week since the Index was rebuilt, although my laptop was rebooted at least twice a day. Now on launching, Outlook 2010 is immediately searchable and Indexing Status says ‘Outlook has finished indexing all of your items. 0 items remaining to be indexed’.


It might be a coincidence, but I recently installed Service Pack 1 for Microsoft Office 2010 (KB2510690) before I rebuilt the index.


Hope the above is useful.
