Question about Outlook Express

Problem began after I performed backup on time machine and reinstall of OS X due to connectivity problems, I now only get Outlook search results from before the back up/reinstall, and I don't even have access to a lot of my word docs.  I rely on the search since I work from home.  All of the items are still there.  The search worked great before I upgraded to Mac OS X 10.7.5 for 10.6.8.  The tech had to copy the whole desktop onto an external hard drive, then reinstall the new OS X 10.7.5 .  Since then, when I search on Outlook, I only get results from before 9/26 (when the backup and update occurred).  The search works great for those items, but doesn't show anything I need for after 9/26.  I tried changing the identity with Microsoft Database Utility and that didn't do it. I've left my MacBook Pro on for 3 straight days, hoping to get the indexing done.  It has gone from 3 months, to 2 years, now at 11 months!  Any suggestions? How do I fix Spotlight with OS X 10.7.5?  Thanks.
