This will work when "Title" is a "TextIndex" (I think, it is).
However, it will then look for titles which contain a word beginning
with "a" and not only titles that begin with "a".

FieldIndex'es currently do not support wildcards. You would need
to implement your own index. If you do, it is easy to plug it into
the ZCatalog indexing framework.
