[Zope] textindex: no numbers appears

[Stephan Abele]

Hello zope-specialists,

i have the following problem:
First, I have created an Zcatalog object.
Then, I cataloged some objects.
The title-Field is indexed with the type TextIndex.
Sometimes, the title of the objects contains only numbers.

The problem:
If the title contains only numbers, the index is empty.

title=3D123  =3D> no value in the index
title=3D123abc =3D> the value is indexed.


Question:
What is wrong?
What have I to do, to index titles which contains only numbers?
Have I to patch some *.py-files?
Have I to use a speciall package?

Because I am a zope-Newbie, every help will be welcomed,
