[Koha] No search results after importing from old system

I upgraded from Debian Squeeze to Wheezy and reinstalled Koha with the Debian packages (http://wiki.koha-community.org/wiki/Debian) and then imported my Library data into mysql. I can access books when I click on a patron who has books out, but searching always returns "No results found" No idea what I did wrong, it runs fine on a laptop.  I cannot see any obvious errors anywhere, but then, I have been wrong before. I have tried everything on http://koha-community.org/faqs/zebra-indexing-wont-work-fix-it-aka-search-st..., still no results. Any ideas are welcome! Marty
