[Zope] - Search engine inside zope database (real)

Hi All, How is it possible to search inside a zope database all the document objet containing a string occcurance (see regular expression) and construct the result in a document with an hypertexte link for each answer? I don't think about the administration tools present by default in zope, at least if I can use this tools.
