[Koha] Upgrading from 1.2.3 to 2.2

[Timothy R.Butler]

Hi everyone,
    I'm trying to take a KOHA install from 1.2.3 to 2.2. 
The upgrade seemed to go OK, but while the tables 
such as biblio appear to still be filled with the 
book data, when I try to look up a book in KOHA 
2.2 using keywords I know exist in the database, 
it always reports that it cannot find anything. Is 
there something I need to do to make the old 
data ready to be searched in the new version?

   Thanks,
            Tim
