[Koha] Curious searching problem with zebra

I'm running koha 3.02.01 on a 64-bit openSUSE 11.3 system with zebra. I have 3 biblios for 'And the band played on', a book, a tape and a DVD. When I search for 'and the band played on', it finds nothing. When I search for 'the band played on', it finds all three. I've done a complete rebuild of the zebra index. Any ideas? -- Bob
