[Zope] Searching catalog via substring

[Reineke]

Hi,

I have got a ZCatalog, named "catalog" and 2 =
automatically-mady-by-zope-DTML-methods "search" and "report".
The "search"-form submits the variable "title" to "report" which =
<dtml-in>s over the catalog.

For example:
http://server.domain.com/report?title=3Dsomething

So far, so good. When the title contains "something" as a word, the =
object is found.

What I would like to do is automatically searching with "*" concatenated =
to the beginning and to the end of the searchstring, so the object =
"something" is found when the user enters only "some" or "thing".

Can anyone point me to the right direction?

Many thanks in advance.
